ipod problem on iphone

[2fat]

having a problem with my ipod on my iphone.
i tap ipod to open it up, which takes me to playlists, tap a playlist to open that up, then whenever i pick a song to play, the play screen goes back to the playlists after about a second.
im sure its something a semi intelligent 6 year old could figure out, but im baffled.
any ideas?

Does it happen for all songs? If so you might want to try re-syncing.
