iPhone Issue

I love my new phone but I have one issue with the iPod part. It has a feature that when you shake the phone the song changes. This is not just an issue when it's in pocket while jogging, but also am issue cause I pretty much dance around my apartment while doing house work. The latest offender with this feature is Wale's "Let It Loose". I know there's a way to turn it off and I think it's come to that.
