Looking for a music organizing prog/app for 16GB Cruzer

Hi, I had an older 16 GB Cruzer (pre Microsoft buy out) that had the U3 app, I recently had to replace it under warranty repair and the new cruzer as we all know doesn’t have nor can it be added.  I use the drive only for my music and video files so I’m looking for an app/prog that is good for taking music/video files from my computer to my pioneer DVD player in my truck.  Any suggestions are greatly appreciated.
