A common area doesn't have to be in any particular place. "/home" is where you go for "your" stuff, but it's not a limitation on you. In my case (and I've noticed in others) I use "/data" for all my "stuff" (music, movies, kernels, other source code). It's on a separate disk from the root drive, and it makes it much safer for me to do upgrades and trial kernels, because if (when) I bork things really good, it's just a matter of fixing the boot drive; not fixing my data.
Consider setting up a "/data" (or your favorite name) partition or drive, and put your media there. You can give all users "rw" access, or give them their own directory, or even define a new group, set ownership to that group, and add membership in this group to your users.
