Right, ActivityPub would really just be the discovery mechanism, obviously you wouldn’t want the actual music to be mirrored to other instances.
If you use a centralized discovery server, you’re right back to where you are with Spotify - at the mercy of whoever controls the discovery server, and shit out of luck if the discovery server goes down. Federation is only confusing for normies because the clients for popular fediverse apps don’t do a good job of making that part clear (or hiding it away).
