No luck. I think before it'll die, I could back up my music to a new computer---is this possible? Any suggestions?

The musics on your iPhone are suppose to be on your computer already since you sync the musics from your computer to your iPhone. Go ahead and factory restore your iPhone, and if you restore your iPhone from a backup, you are probably going to experience the same issue again so i will advice you to not restore from a backup after factory restoring your iPhone.
