Thank you guys so much for taking the time to give me some feedback! I really appreciate it. I'll make sure to address those issues--didn't realize the app itself was confusing to use, great point.
"Power hour" is a popular drinking game where a group of people gather and put on a power hour playlist. The 'game' is played by setting up a playlist to play one minute of each song for 60 songs (= 1 hour). Once a song changes, everyone takes a sip of their drink/beer.
The app is supposed to make it simple to setup these playlists. Often times, people make power hour playlists ahead of time and it can take a while. With this app, power hour playlists can be made instantly and on-the-go with an iPhone. Does that give you a better idea of the intent?
