It’s called the Couch Music Player, appropriately. It’s an easy-as-pie way to make and modify playlists from the music you have stored on your iPad.
I was goofing around with it while pretending to watch TV with my wife last night (sorry, dear, but I’m just not into The Good Wife) and after a few minutes, it became rather addictive.
Searching for songs/albums/artists is as easy as a swipe. Playlists (as many as you want) are created by a simple drag’n’drop with a finger. And if you miss iTunes’ cover flow, there’s a facsimile of that, too.
If you spend time listening to music through your iPad, the Couch Music Player is far superior than the native iOS app. And for $1.99, it’s worth a try.
