Could you use your fame to get last.fm to extend their API to allow listening number checks so it's not only people who registered with your bot? ;)
Also thanks for your work, while I dislike the spammyness of it, that's on the server owners (main server I'm on limits it to one bot channel)
Last.fm isn't really expanding their API unfortunately. You can however see Last.fm stats in the main artist/album/track commands.
As for spammyness, I'm aware this is an issue. For non-bot channels I recommend using .togglecommand and enabling just a few specific commands, and setting a small embed mode so .fm commands don't take up too much space in chat.
