The Catalog System

The Media Player Mixer Express™ (MPMe) can perform very fast because its integrated Music MegaBase® Catalog SYSTEM is designed to take advantage of the natural connections between thousands of hit-music tracks.  The connections are established by storing, and then comparing, track (song) attribute information (or catalog CONTENT).  The MPMe uses the database power of Microsoft® Access to manage these track connections.

For example, the MATCH filter capability in the MPMe allows users to locate one track by an artist such as Madonna, and with one-click, instantly view every available track by Madonna (see image below).  This is possible because the Music MegaBase (MMB) Catalog system maintains the common attribute links for each track, and can easily apply a mask to show every system-registered track on your hard drive that shares the same attribute.

Here are more catalog attribute examples: with one mouse click, users can easily browse a list of all 1970s era "disco" tracks, or every slow tempo track, or every track on a named playlist—and then quickly construct a music set comprised of those tracks.  Click here for access to sample music lists created for DJs by the MMB DJ catalog content in the MPMe.

The Power of Catalog Suggestion

The catalog system in the Media Player Mixer Express™ uses natural suggestion to help DJs find their next music track—even when they don't know what they want to play when they start their music search.

In the same way that a patron can walk into a fine restaurant, browse a menu of alcoholic beverages and see beer, wine and liquor—and then pick from wines grouped by red or white varieties—the working DJ can use MPMe search technology to identify and choose from a variety of related music sub genres stored in the catalog system.

To illustrate the power of suggestion, look at the Music Type category "Soul".  It has several catalog Music Code sub classifications that enable a more granular genre identification process.  "Funk", "Motown" and "R&B" are three Music Code categories currently grouped under the "Soul" Music Type.  In a broad context, most music editors would probably classify Diana Ross and the Supremes as 1960s era "Soul" performers.  However, this "soul" group produced a rich legacy of hit music which many people also recognize as "Motown" music. 

When you use the MMB Catalog system in the MPMe to show matching sub genres, the DJ can instantly see and select from any "Motown" hit he might have on his computer.  This can be handy and FAST if you're playing the retro hits and need to find like-sounding hits in seconds.  To execute, when browsing "Soul" category hits, simply press the Music Code filter button on any "Motown" oldie title track to reveal a treasury of hits by other Motown artists such as Smokey Robinson, The Four Tops, and Stevie Wonder—assuming that you have the digital audio files associated with these titles on your MPMe computer.

The MPMe makes the most of the natural connections—the common attributes—of each song; connections stored in the catalog system.  The process flow diagram at right illustrates how the shared attributes of songs can be instantly evaluated by the search engine in the Media Player Mixer Express™.

It is this powerful search feature in the MPMe—the process that SHOWS these connections to the DJ—that gives the software the ability to "suggest" music tracks.

In this diagram, the RED box depicts a query search starting point of "Dancin' In The Dark", an up-tempo rock song by artist Bruce Springsteen.  As you can see, the track contains the following stored data attribute values:  the Artist is Springsteen, Music Type is Rock, Tempo is up, Gender is male, and the Year of Release is 1984.

Using a catalog system enabled MATCH filter, DJs can easily find songs of similar sound or style.

The diagram shows, for example, a blended attribute query that has returned results (indicated in each GREEN box) such as "Two Tickets To Paradise" by Eddie Money, "Small Town" by John Cougar Mellencamp, and "American Girl" by Tom Petty and the Heartbreakers.  Each of these tracks are songs that, like "Dancin' In The Dark" by Bruce Springsteen, are up-tempo rock tracks with male vocalists.

If the catalog content contains YOR (Year of Release) data for like songs, it is also possible to narrow the results to songs that were popular in the same year and decade.

And from there, users can continue the application of the MPMe natural connection suggestion feature by locating all similar songs with the same tempo.

The current build of the MMB DJ starter catalog contains pre-populated track information for Title, Artist, Music Type, Gender of Lead Vocalist, Tempo, Artist Type, and Dance Rating for every track in the catalog.  It may also contain additional track data such as YOR (year of release), Set Name (pre-designated by catalog author) and Music Code (which is a music type sub classification).  See notes below regarding scope of the catalog content and its typical music genres.

Populating the Catalog System with Attribute Data

When Media Player Mixer Express™ (MPMe) users search for a music track they want to play—they are searching in the integrated catalog SYSTEM.  With the MPMe, users have two ways to make sure track attribute CONTENT (information) is in the catalog system:

1) Users can physically input basic track attributes such as Title, Artist, Music Type, and Decade by using their keyboard to enter the data.

2) Users can acquire the optional MMB DJ catalog CONTENT, which is an organized list of hit-music tracks including approximately 4,000 entries covering 28 music genre categories (and subcategories).

The catalog system is designed to merge title and artist information entered by the user, with existing track information available in the starter catalog.  In this way, the Media Player Mixer Express™ allows users to shape their own music track list, and it also provides access to the optional starter catalog content where specific track attribute data is already present in key categorieswhich can save users MANY hours of data entry time!

MPMe users who do not acquire the optional starter catalog* can still benefit from the full organizational power of the catalog system, but they will be required to enter some basic information about their music tracks—BEFORE they can search for, and then play, the tracks in the Media Player Mixer Express™.  To get started, at a minimum, do-it-yourself catalog builders must enter track data in these categories:  Title, Artist and Music Type (genre).  Once that information has been input into their catalog system, the search engine can find the desired track very quickly.

So, at the very least, a user who did not acquire the MMB Catalog content, but wanted to input track attribute values (data) for a hit music song such as "Fool, I'm A Woman" by country recording star Sara Evans, would be required to enter this information in the catalog editor screen:

Fool I'm A Woman (in the Title box), Sara Evans (in the Artist box), Country (in the Music Type box), 1990 (in the Decade box), and HMT (for hit-music track, in the AFC--Audio File Content--classification box).

Contrast that with a user who has acquired the MMB Catalog content option.  To begin accessing the catalog content, users enter their unique catalog activation key and then press one button during set-up to allow the catalog content.  (Complete instructions are included in HELP screens within the MPMe.)

After allowing the catalog content, a DJ will have an entry for the same Sara Evans track.  However, the attribute values will also include additional information*:

In this example, "Fool, I'm A Woman" by Sara Evans is in the "Defiant Hearts" music set which also contains other songs such as "Go Where You Wanna Go" by the Fifth Dimension, "Stop Draggin' My Heart Around" by Stevie Nicks, "These Boots Are Made For Walkin'" by Nancy Sinatra, and "You Don't Own Me" by Lesley Gore.

Because the catalog content for this track contains a wealth of attribute data, it can be easy to use the MPMe filters to find similar music.  For example, searching by the Music Type category key will display a list with all Country genre tracks.  Or, clicking on the MATCH Music Code button from the MPMe screen will show all songs that share the same "GirlTalk" Music Code value; and pressing the MATCH YOR (Year of Release) button will restrict the list to all tracks from 1998.  In this manner, the user can narrow or broaden the search to suit his taste.

*Not every track listing in the current MMB DJ catalog will have the degree of data field (attribute value) population illustrated by this example.  Some will have less values present, some may have more.  Of course, users can always choose to add more information.  Catalog content is subject to change without notice.  (Read beta release notes before adding a large amount of custom information.)

Catalog Scope

The current MMB starter catalog content option spans part of 8 decades—covering the years 1930 through 2007.  However, to be more precise, the catalog, in its current form, is weighted to hit-music titles and related information from the 1960s through the 1990s.  This means there are plenty of listings for the hits of the '60s, '70s, '80s and '90s; and a relatively small number of entries for the 1930s, 1940s, 1950s, and years 2000 and later.  (Future upgrades may add more tracks and information for these "light" decades.)

The most broadly represented catalog Music Type (genre) is "Top 40" (which is has been used to identity songs as generic "radio" hits). Other music types include: Rock, Modern Rock, Disco, Country, Folk, Novelty, Rap and so on.

If your typical DJ party audience will appreciate a balanced mix of "hits" from the 1950s through the 1990s, and, for example, does not require a heavy selection of rap or techno or reggae genre tracks, you will immediately benefit from the stored attribute data in the MMB DJ catalog.  (Of course, you can always add information for any type of music track to your copy of the catalog.)

In particular, the MMB starter catalog content option includes data for these attribute categories: Title, Artist, Tempo, Decade, Music Type, Gender of Lead Vocalist, Artist Type (whether solo artist, duet, or group) and MMB Dance Rating (the catalog editor's subjective ranking of a song's ability to inspire audience dance participation, where 1 is most likely and 5 is least likely).

Also, some track entries additionally contain information in other categories including: YOR (year of release), Set Name (pre-designated by catalog author) and Music Code (which is a music type sub classification).
