use to have a htc m8 with nova launcher and never had a problem with my lock screen when playing music i can forward or pause/play on the lock screen with either pandora/spotify or any mp3 app, with my s7 i can only get my lockscreen "widget" i guess you could say with my mp3 player app.. really want to figure out how to get my pandora/spotify on my lock screen so i dont have to unlock my phone every time i want to change a song. any help would be really appreciated i will post a screen shot of what im talking about soon my s7 is in the middle of a SW update
