How do you change song names in your V-Cast music library on your phone?

I have a Samsung Rogue (absolutely great phone with not that great battery life). I sync-ed my phone with the computer and it downloaded all the songs I had on iTunes. The thing is on the computer, the songs have all the song info like name and singer, but my phone's music library shows them all as unknown with the song names as ';????????';! This is so annoying and I can't find any way to change the names. Help!How do you change song names in your V-Cast music library on your phone?
