I have a new LG Chocolate 3 and I'm trying to add music files from my computer to the phone. Do I have to pay to use VCast Rhapsody or is there some other way to transfer my music files to the phone? I tried connecting the phone to my computer with the USB cable and using Windows Media Player to transfer the music files, but I get 'an error occured' under 'Status' on every file when I click COPY. What am I missing?
