Elleo: I quickly compiled your git tree and tested on device, unfortunately it seems not beeing able to play any songs, it browses the lists quite nicely and artist graphics comes up. So some tweaking is still needed.

Small improvement hint would be in PageStack disable backnavigation back to login page, or use replacepage. (And there is continiously running animation on the login page eating cpu (animation disable after succesfully login would be nice, or remove login page from pagestack)).
