Query: Don't waste your time...

SanDisk's mini-cruzer jump drive works beautifully as a storage device...and that's wonderful, but SanDisk is a pro at making portable storage...not digital audio players.I purchased this despite the negative reviews, only to find that everything was true...the player skips on audio files that play perfectly fine on the PC and it will freeze when you try to move to another track.There is no way to shuffle the tracks or create a playlist...this player is even worse than early-generation MP3 devices. I felt like I was going to break it.
