Is there a way to use the slice as a jukebox? Do I need a 3rd party app for that?
Are you able to elaborate on what you're trying to do?
I just want to play music. It just shuffles all my music. Just turn in on when there is a party and don't have to manage it any more.
There's a Party Mode, which I assume does the job. In your Music Library list click the centre Left single arrow on remote.
