Major issues on 7.0 Stock 7.0 on Nexus 6p and Pixel C: on Pixel  no songs will play. The app skips through the whole playlist in a continuous loop without playing anything. On Nexus  the app will play songs when it's not asked to  play in the background when it says it's paused  and play two songs at the same time when it's told to play.
