1. You should be able to attach metadata such as beats-per-minute or key signature to each track, so it's easier to make remixes of tracks from different songs.
2. It would also be great if you had support for formats which include per-note data like MIDI, Lilypond [1], and MOD/XM/IT. Bonus points for built-in scrolling sheet music and/or Synthesia view [2].
3. If you have an MP3 of each track, then mix them together to create another MP3 of the final song, your data is going through the lossy MP3 encoding step twice. Maybe you should have an option to store music in FLAC; perhaps a perk only available to premium users (since it takes more resources).
4. Content creators really want to find music to use in Youtube videos, phone apps, games, whatever. People who upload songs to this should really have a way to include license information. Bonus points if there's a search or RSS feed for music by license type.
5. You should be aware of DMCA compliance. If this app becomes successful, I have no doubt that people will try to upload copyrighted songs, and you'd better have a plan for dealing with takedown requests.
