hey, try some of the mars volta's stuff. they have some pretty weird sounding stuff but some of it is reaaalllly good :)
or if your music department at school lets you you may be able to pull the layers apart and take the vocals of a track. it takes a lot of fiddling tho.
u can pretty much link anything back to belonging. it just depends how u word it. but dont pick one of ur fav movies or anything cos then ur more likely to get off track without even realising.
