Nice work, I did pretty much the same thing about one and a half years back [1]. Didn't know it's still running [2], haha. I built it because I liked Favematic [3], but thought it didn't have enough "radio" like functionality.

I like your visual design better though, it's way cleaner. Also the track is better presented, but then again there were no pictures for tracks when I started.

Edit: Oh and btw I also had no clue how to describe what it does succinctly ;)
