Constant Crash in Background

Possible Helpful Information; iOS 6, iPod 4th, Updated to version 2.0

When I do lock my iPod, or play it in background, the app just crashes. Every about 6-10 crashes in background, I eventually do get it to play my downloaded content fully, but it crashes way too much. please let me listen to my content on the first try in background.

Ohh, and if you could organize your downloaded content by holding and dragging, that'd be great.
