It would be useful if there was a channel (or forum) that linked multiple resources for copyright-free test acapellas and covers (either made by AI Hub members or somewhere abroad) to use for AI generation. (This is mainly so it's easier to source test audio that the RIAA won't be pissy about)
I envision it to use The Creative Commons 4.0 License (https://creativecommons.org/licenses/by/4.0/legalcode)
