I haven't noticed it when playing mp3's, but I haven't really done that much. But Pandora messes up a lot. In addition to songs sometimes being jumpy, sometimes getting "stuck" (sounds like a record with a scratch and it plays the same few notes over and over), every so often the end of a song gets cut of and it proceeds to the next one. And it sometimes skips the next song to go to the following song. Baffles me. So yes, I've experienced your problem, but don't know what's up. And I'm usually playing it in an area that has mediocre cell coverage but good wifi strength. Don't know if that has anything to do with it.
