My Question or Issue

 I'm playing Baauer - Tep Tep on Spotify and last.fm is scrobbling Ducky - Love You Just The Same. When I play Ducky - Love You Just The Same it scrobbles Baauer - LuckyMe Advent Calendar 18.

Obviously some wires are crossed. I've already posted on last.fm's community page but it looks to be more a Spotify issue.

Why is this happening and how can I fix it?
