hi there. got a new car last night and tried playing my music from my Spotify account. it stopped playing after around 20 seconds. it's never done this before. started glitching on the cars screen. i even tried playing music through aux cord instead of Bluetooth and it still freezes. why?!?!? my iTunes Radio and Pandora play just fine. i even deleted app and logged in again but it's still not playing music all the way through. help!
