Default Anybody figured out why Google Play Music keeps giving random errors on KitKat?

ever since i upgraded to stock kitkat (not via ota, and i have root) my google play music has been giving me unable to play this song errors. i'm down to do a logcat if someone smarter than me is down to read it and try to find a solution. i've noticed it when i'm on wifi and mobile data, while i'm using gps and while i'm not, with personal library songs as well as all-access tracks, and i'm fairly certain it hasn't mattered whether the tracks were on-device or streaming.

has anybody who took the stock kitkat OTA without any root or modifications had this same issue?

has anybody had zero GPM errors since updating to kitkat?
