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.

Just one admin's opinion, but I think the bot spam thing is more a matter of server etiquette than anything. Sure, I'm all for #bot-spam channels, but nobody looks at those unless they're using it, so it's not very useful for things like sharing last.fm stats. I'd much rather people use it sensibly in a #music channel.
