Not really a third-party app as it's by Spotify but had no idea what I should flair it as. I was in the top 4% of Olivia Rodrigo listeners, what'd yall get?
edit - answering questions
this was sent by Spotify's twitter account [here] and from the looks of things was mainly made to promote the today's top hits spotify playlist, hence the minimal size of the artists that show up. So if you listen to anything other than pop sucks to suck I guess, still a pretty cool feature and I guess wait for Spotify wrapped or connect your Spotify account to last fm. Cheers
