Sorry to get hyped; sometimes text doesn’t translate intent, and I felt like I needed to defend my position.
We don’t get credits on the credit roll per say, only the library gets official TV screen credit. But, if you are shopping your services you can say you wrote on the show, and if someone really needs to see it, you get quarterly royalty reports that name the episode and show.
As far as beat: I’m looking for kick, snare and hats and a percussion track. Something simple, that has a nice turn around at the end of the loop. No melody; synths bass guitar etc. (main reason being to avoid potential law suits since I have no way to guarantee you didn’t sell the music before or after). In fact, as a further safe guard, I often sample replace your pattern and tweak it a bit. Safety first!
