1. Trax Better Mp3 Organizing Through Visualization

2. Motivation “Organizing CDs or records is a *lot* more fun than organizing computer files; that's just a proven fact!” –Chuck Eddy, Senior Music Editor, The Village Voice My humble attempt to help poor music obsessives out Create an editable and browsable map of the genres & styles of an mp3 collection

3. Design Goals Who is it for? –Music enthusiasts (not for the casual fan!) What actions does it aim to support? –Browsing through interrelated genres and associated artists –Creation of playlists –Labeling of mp3s’ genre, and other information What dataset will it function on? –Any large set of mp3s –Test dataset: my own mp3 collection (~7000 tracks, 50+GB)

4. The Visualization Key concept: most songs exist within multiple genres (eg, Rock & Post-Punk) Build graph of genres, with links between genres that are associated with the same song Force-Directed layout based on number of mp3s within a given genre

5. Final Product

6. Demo!

7. Pros Spatial position of nodes reflects real-world genre relationships Wide range of filtering and viewing options to manage size and complexity of graph Playlist creation is easy

8. Cons Requires large initial investment of time to sort and label all mp3s May not be able to link all genres together (creating outliers & islands) Sometimes hard to find particular genre with all genres showing (search would be nice)

9. Peace.
