Sync'd music won't show up in Music Player
I just copied a CD onto my computer hard drive using Windows Media Player. I then sync'd the CD to my Pre Plus. The CD's files are physically on my phone. I can see them when I have my phone plugged in as a USB drive, and I can play those files on the computer. However, when I turn off the USB drive and am back to regular phone status, I cannot find the CD files anywhere in the Music Player. I'm sure that I used the same method to sync up the CDs that are currently on my phone. What is wrong? HELP!
