I really like this. I'd say the only thing I'm missing is being able to make custom playlists like Spotify. I think there are plenty of people who still have their own music that might find this useful, but I have no idea how you might reach these people.

edit: I may have found a bug? I uploaded multiple remixes of a song and it only shows the original version. I don't see a way to see what raw files are being stored, which I think would be incredibly helpful.

edit2: Oh, I guess it just generally isn't properly showing new songs atm. Ah, well. I'll try again later.
