Corona virus online covers

I noticed in Ken's recent video about his life (very inspirational!) he mentioned that now is the time to get yourself out there , meaning posting your singing online while people are home and watching a lot of online videos.

I also noticed that on facebook, it seems like everybody and their brothers are covering songs while they are staying at home. I double everyone is purchasing pricy copyright/mechanical licenses, so I was wondering, did Facebook relax their policy on people posting their covers? It doesn't look like any are being taken down.

I have some audio clips of our band (no video) and would like to post them on our band's Facebook page, but don't want to violate any policies.

Thanks very much for any insight/info you might have.
