No wonder it couldn't find anything for most of the artists I tried, then, despite a whole lot of their stuff being on YouTube... And for the one it did, the song matching seemed incredibly spotty (try searching for Huoratron and playing the song A699F, for example).

Some other feedback: You should probably add some tooltips (I assume the circling arrow on the far right of the bottom bar is for "repeat" but it'd be nice to have a tooltip confirm the assumption), and for some reason the volume slider seems pretty unresponsive - you need to hit it in a rather exact spot to set the volume automatically to a specific level.

(This should be higher up)
