I can't delete a song from the list of all songs. How do i highlight it and then choose delete? As soon as I tap it plays. I don't want it to play and i don't know the artist name because I haven't listened to it before I just transfered a bunch of music from my pc that I got from Nexus radio. I figured I'd just delete what I don't want. Plugging in the charger renders play button not working on media player widget sometimes.
