iPod Feature Crashes

I've been noticing recently that my iPod feature on my iPhone crashes almost every time I use it. This happens most often, but is not limited to using it in cover flow mode. After noticing this on various occasions, I tried three times in a row and could not get through the first half of three different songs before it crashed. Not sure if anyone else is experiencing this issue, but I'd like to hear some feedback on this problem and any possible ways to stop or at least limit it. It's pretty annoying when I'm trying to listen to music (NOT while using any other applications/features) and having it crash on me. Thanks in advance for any responses!
