I agree in theory, but I think that breaking the mold slightly will help it grow past a cool tech demo.

I'm mainly comparing this against using SoundCloud directly, or something like turntable.fm. A big feature I like is being able to +favorite a song that I like, or buy the album, so anything that causes me to lose context greatly devalues the app.

And for the cookies, it's really just the background and comment preferences. Maybe the cookie could be named .cmdfmrc or something?
