But is this even possible? Am I just asking for trouble? Should I start over and rebuild this computer from scratch (an incredibly annoying proposition)?
If you repartition the disk you lose all the data. If you were using Logical Volume Management (LVM) for all you partitions and hadn't assigned the whole disk you would now be able to use the LVM tools to increase the size of one of your partitions. If it were me I'd just buy another hard drive.
Another option is to mv some of your music directories to somewhere under / and symlink them back to their original locations. That way all your apps can still find them but they actually live on / using up some of that 63GB of space.
mv /var/Music/MusicFolder1 /NewMusicLocation/MusicFolder1
ln -s /NewMusicLocation/MusicFolder1 /var/Music/MusicFolder1
