I had suggested your little hard drive as a seperate /home, but it'll be far too small for that. How about (depending on the size of your collection, of course) using it for ogg/mp3 storage? My collection is pretty big, but I'm looking at using one of my old 6 or 10 gig drives for that (frees up a little space of my 100gig /home partition and will make backup strategies a little easier).
