1/2: It's a new space and the wild west for sure. But for music there are a few avenues for it. I like what Avenged Sevenfold is doing with their's. They have been heavily in the space and are looking to do exactly what Eno said.
2/2: They're using their nft's as their fan club membership. They all include perks such as a vip entrance at concerts, seperate merch line/discounts at shows, special channel in the discord where the band hangs out, giveaways, etc.
