Anyone here use roboyoshi's datacurator-filetree? What do you think of it?

I write and record some my own music, some is personal and some is for my band. Under this filetree, where would it go in your opinion? In audio? Or in documents? Should I have all "band" media together, music, artwork, plans? etc? Should I have the band as a user on it's own and let it use it's own filetree?
