Sansa Fuse 4g refuses to play most of my music.

Hi, recently I manually deleted some albums off of my sansa fuse through my computer (to make room for new music) and immediately afterwards half of my albums left on the fuze wont play. In fact, one of my new albums, PJ Harveys, A Woman a Man Walked By, plays in half speed and sounds distorted and insane. So, if you have the brains to help me, cuz i obviously cant help myself, I would very much appreciate it.                                     Jz-Royal or MeowSter~

1.) Try a reset. Hold the spring-loaded power switch up for at least 20 seconds. Release, then power on & try it.

2.) Run ChkDsk to check for and fix any corruption.

3.) Format the player and re-load it.
