Yeah most feeds have keysend so users need an Alby wallet to send sats. Fountain has started hosting music now and they use lnaddresses in the feeds so you could probably add those.
PC 2.0 has always used keysend but everyone just uses Fountain which does keysend payments so no one knows this is even an issue.
We either need more wallets to support keysend or people to change what's in their feeds.
