There is this: https://www.kompoz.com/ https://www.kompoz.com/ It's geared more towards collaboration and there is some system to share any income that gets derived (not sure how it worked). You find someone's song page, download the existing tracks (stems) and work on your own, uploading to the collection when you are finished. I collaborated with some artists and it was fun and I met some folks. They set up payments but I never expected anything to come from that. I thought finding projects that are interesting to collaborate on was difficult. It's just a big pile of music of varying quality and genres.
