i am trying to become a music supervisor or at least get my foot in the door of a company that does so. actually, i've explored some of the links you've posted in more detail, and they are pretty helpful.

filmmusic.net actually has a job listing which is great. unfortunately, it's only available to paying members. it might be worth the money to subscribe though.

the other, filmmusicmag.com, actually has a free film music job newsletter, so i'm definitely gonna subscribe. i think i just need to do more research.

once again, thanks a million.
