I'd be much more likely to donate money for a track/album if I had some automatic way of tracking which I had donated to. One way to do this would be a website that let you donate a suggested amount for a song or album. For each song/album you donate towards, you get some signed key that says you supported that song.
There's some interesting things that you could build off of this:
- Media players could show a little badge whenever you're playing a song you've donated to. They could also remind you (if you wanted) when you listen to a song frequently but haven't supported it.
- Hook into Facebook - when someone downloads a song, they can see which of their friends have donated to it.
- An additional metric for music suggestion services. What better way to show you like a song than by putting your money where your mouth is?

3. If you use Google Docs and Dropbox, you can keep everything in one place.
