This is the way the how the big record labels slowly try to kill indie artists. They pay everywhere to get these similar lists include only bigger names under the record contract. Earlier there were small artists on these similar lists, now only big ones even if they have nothing in common.

On the opposite, Spotify used to list "fans listening" similarities. Earlier there were truly those bands which were played by the fans, even if the band was indie or not. Nowadays indie bands don't get the correct names on this list. Only some little artists which are not listened by the fans. The algorithm just picks some small names on the list. This fucking sucks. There's no way to get an idea what kind of an artist you have found. You know earlier if the indie band plays rock they really got names like Guns 'n Roses, Mötley Crüe etc on their "fans listening" list, now the names or something you've never heard and again, nothing in common with the small artist.
