App is exactly what I was looking for, on-the-fly picking of songs to play during a party or dinner. What it needs is an on-screen volume control and airplay button. Got around the airplay functionality by running the standard music app, choosing the airplay speakers I wanted. Then going to Party Jukebox and selecting the songs I wanted. Fortunately it 'remembers' the redirection to the airplay speakers.
I also have no idea what the two icons at the bottom do. They look like 'playlist' and 'edit' icons, bit are dimmed on both my iPad and my iPod touch. Maybe it's something that 'broke' in IOS 5.01?
Otherwise, I like this and will recommend to some friends that were asking for this type of jukebox app.
