There are many podcasts that exist on Google podcasts but aren’t listed on YouTube music. Maybe around 20% of my podcast collection doesn’t exist on YouTube music; and they aren’t fringe podcasts either. Many are very mainstream. This makes YouTube music an inadequate replacement

You can directly add podcasts by their feed URL. They don't have to be on YouTube music. The discovery for such podcasts is non-existent, though.
