Artist/Song mixes

If i listen to a song and it pops up on stats.fm, sometime it shows that its the live version yet I didn't listen to that version, and sometimes multiple songs have different covers, or made by a different artist. When listening to Black Star By Radiohead, the app mixed Rosie Carney into the actual song even tho she just sampled it during the pandemic, and the cover is HER cover instead of radiohead cover
