My producer, Neigsendoig, has some music you could use. Just search up [at]Neigsendoig using an Invidous instance, and put on a playlist or album of his music. He doesn't mind if people uses it as long as he's credited.
I'd only recommend the ones with CC BY as the license, and maybe you could use Wavlake in order to ensure you can credit him properly.
That's been challenged by UMG or Warner I think.
