Thank you! Last.fm was a huge inspiration for Rocksky. I still think scrobbling and social listening are some of the best ways to discover music. Hoping to bring a more open and modern approach to it with ATProto.

If you can a find a way of A) getting live scrobbles from Last.fm into Rocksky without having to change the clients that are all using Last.fm already and/or B) get historical scrobbles out of Last.fm into Rocksky, I'd think you could potentially take over the ecosystem relatively quickly :)
