@simon-weber What are your thoughts on this? My previous method of returning tracks was [as a class](https://github.com/dpogue/gmusic-daap/blob/master/googlebackend.py#L79-134) but that runs into issues when the two APIs return different key names.

I'm also not sure how much responsibility you wanted the API to have over the data compared to the user. Right now it's up to the user to parse/store the track dictionaries.
