I'm having issues syncing music to my captivate. I first tried to just copy them to the music file on the phone through my computer and it worked for a few songs, but was very slow and then I couldn't delete them afterwards (displays an error message about being writes protected) and they are still there and I cannot get them off. Also I tried using Media Player to sync more songs to it and when I did it said it was finished but the songs do not appear and the amount of space used stays the same as before. Any ideas (mainly how to delete the songs that I have already put on)?
