background musics for tv show

Hello.

I need help. I'm making a tv show on my own and I can't find those background musics, kinda like this one :

Where could I find some of those ?

Thank you.

On second thought, don't check out NIN. Their stuff is well copyrighted.

Check this out instead. It may suit better without upsetting wolves wearing suits.
1940s Film Noir music

Thank you, but I was looking for musics which have been made to be used in animated tv shows as background musics, and that are so not used in any for now. I mean, not music from old shows, more of music similar to background musics of recent shows, which you could download on a website.

Still thank you.

It's a show about nothing...a show about nothing would be very successful. I would estimate that it would air for roughly 10 years and be very popular.

It's a show about demon, me, an angel monster hunter and an elf, in a medieval-steampunk world. Mix of the owl house, hazbin hotel, and more.

use better days

I think I found a few musics. When it comes to the rest, I'll have to pay someone, if my show gets financed.

Thank you.
