What the hell is going on

over the last couple weeks I’ve noticed last.fm will scrobble random songs on my account? Mostly stuff I’ve never heard of, but sometimes if I had checked out the account ON SPOTIFY but didn’t play anything, a couple hours later I’ll see a bunch of strange scrobbles and some will be from that same artist I looked at earlier. WHAT is the explanation and is this happening to anyone else. I attached some photos and the deleted (greyed out) scrobbles are the weird ones.
