CloudMusik is a 3rd party Google Music app for Windows Phone that fills a void left by Google who still refuse to support Windows Phone and the app has just been updated. Version 22.214.171.124 fixes crashes when playing pinned artist, albums or playlists plus it also fixes failures when playing cached or searched songs. The app is due a bit of a UI overhaul and hopefully that will be coming soon.
The app costs £0.79 in the Windows Phone Store.
Version 126.96.36.199 features:
*Fix for crash when playing a pinned artist/album/playlist
*Fix for failure to play some cached songs
*Fix for crash when playing a searched song
