The prioritization feature is great because, at least on TouchTunes, not even the owner can skip a prioritized song. Unplug the machine and it’ll just resume the song when you start it back up.
Nothing took the wind out of obnoxious drunken revellers quite like what I called The Hard Reset: Miserere mei, Deus followed by Feels So Good followed by the 3 or 4 longest Allman Brothers Band songs available. It worked best when they had Mountain Jam.
