As solo game devs, do you use stock music?

Hello everyone. Im a solo game dev working on my first commercial game. I’m an experienced programmer and I can also do pixel arts that are just good enough for my game. However, I found myself unable to do musics and SFXs. For sounds, I bought a bunch of stock sound effect packages and I feel like those are good enough. But for things like music, I’m not sure about stock musics. I always have questions in my head like what if there are other games out there using the same music. So as fellow solo devs, do you use stock music? Or do you know any remotely successful game that uses stock musics?
