The album A Different World isn't from the metal band Kamelot but from Famous Dirtbag Da Prynce of Kamelot and all the songs from that album seem to have "Kamelot - " in their title which isn't the case currently.
Contact the Artist Support. I did and they had fixed my albums in 2 days.
I'm not an artist, just a random user, not sure they'll even ear me out on this :)
I am sure they will if you point them to the right discography of both artists that would be a proof of the correct assignment of albums. :-)
Happens too often UFO etc has wrong tracks linked to it.
Suggest Spotify use genre as well as artist.
Same for a band called 'Bombay', lately these albums from some russian artist have been showing up on their spotify page which are definitely place wrong.
