• 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, 50GB)

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

Final Product

Demo!

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)

Peace.
