Did you actually need the music?
My point being, sometimes you get an offer that makes you mind bend twist and turn, but the true answer is: it wasn't part of my plan and the only reason I'm considering now is because I've got an offer.
I tend to turn down most if not all such offers and get back to them if I have a project (any) that actually requires their services...
Yup, I need music, otherwise I wouldn't accept the offer. Thanks for the warning for the future if similar thing happens
