Stops playing after 1 1/2 songs~

I can't figure this out, I've been using L/W for a long time now, and I have never had this problem. It doesn't even happen all the time. I've searched all over L/W and these forums for an answer, but can't find one.

I can fast forward to the next song in my queue and then rewind and it plays that song, then a bit of the next one. But not continuously...sounds confusing, I know! Hopefully someone knows what I'm talking about! lol

Thanks!
