Why are the songs on my Zune playing in slow motion?

My Zune was working perfectly fine, but now for some reason the songs only play in slow motion. Is there a way to fix this or am I screwed and need to buy another or something?Why are the songs on my Zune playing in slow motion?When the music on my Zune started playing wierd I erased all of the music and resynced it. That solved the problem.
