are you sure it's the same instance of a song? maybe it counts as a different song because it's from a different album version?
Why is it possible to add the same song multiple times to your favorite songs on Spotify?
No, it was the exact same song from the same album, but I guess, it must have been a bug, because I fail to replicate it atm. I wanted to upload a screenshot when I made this thread, but kc was a buggy piece of shit like always (showing that I was banned since 2020 for whatever and such), so yeah...
