I'll also add in this website I remembered existed while answering that. You pay once and get a license to use the music as you need. If you are familiar with astlibra the music in that game is entirely comprised of free music between this and dova-syndrome with maybe one exception that comes from the unity asset store and another song that the developer commissioned himself.

Honestly? Speaking from experience I would give up on hiring a musician unless it is something you absolutely can't relent on or you are willing to kickstart the money to hire one. If I could do it again I wouldn't have ever hired anyone
