Outdated but does work. Needs some further options.

Tried this on 3 different devices. Finally got it working. You HAVE to make and populate 2 new playlists. Arena Sounds and Arena Music. I made those in iTunes and synced them onto my phone and the app works. It does need a refresh and some further options, but it does make the soundboard easy.
