i cant think of any ways that can change the destination of your music files, but you can try on SSD
Don't forget that you need to set this in itunes as well, as Itunes automatically builds its own library for music files as you put them onto your hdd ( especially if ripping through itunes direct from a cd)
you need to go to Edit menu, then prefences. under the "advanced" tab at the top you can specify where the location of your itunes music folder will be, make sure it's pointing to somewhere in your hdd and you're golden.
