The intersting part is that if it rebooted it would continue to play only the current playlist. If you tried to switch the playlist sometimes it would give that stall of the music, where it would appear that pause was not on but would not play any music and timers stayed at the beginning of each track. Stragely enough eventually if I picked a playlist it liked, it would begin playing. It seems like when it is playing alpha 6 is pretty stable, but if you get stuck in one of the reboot modes , or this stopping of music it just gets sort of ugly.
