I downloaded 8 new songs. These are MPEG-4a format (not protected). If I access my music folder via the USB drive I see all 8 songs and can play all 8 songs through the computer.

When I try to access these songs through music>song list only 7 of the songs are there. These 7 play fine. Where is the 8th song? If it shows up when I hook up as a usb drive then it has to be on the phone somewhere, right? So why cant I find it in my song list?
