Perhaps Deezer is referring to the ratings of the Super Mario "series".
The first one did well.
The second one, being less original, didn't do as well.
SMB3 was much better.
Super Mario World, or "Super Mario 4", was considered the best.
I'm probably wrong, but... well, I'm probably wrong, and that's all I can say!
