Not really an issue, but I noticed when you change the last parameters in the url, in this case, the parameter s130 to for ex. s400, you'll get an album art image of size 400x400 px. Could this be implemented as a function like api.Api.getAlbumArt(songid,size) ?
Nice find. This seems reasonable to me, and would be a nice chance to investigate #38 as well.
Quick heads up: I have this working (along with #38), but it'll be a little bit until I actually push it. The protocol doesn't fit into my (terrible) old code, so I'll put it up with the major refactoring that's on the way.
