With music? Hell no, what makes music good is completely subjective. Now video game reviews matter somewhat. I'm not just saying that because I review games for a living, but a bad game is unplayable. The controls feel stiff, it's filled with glitches, etc. No one would give Superman 64 a high rating, it's obviously broken.
But a terrible band like *insert shitty scene band* could get a 9/10 from a reviewer. Is that reviewer wrong? No, because obviously they like that kind of music. Another example is this, you can hand someone the most critically acclaimed hip-hop album of the year, and they could think it's terrible because they only like country music.
It's easier to rate something that's interactive.
When I review albums, I base my reviews on 6 criteria: Lyrics, Musicianship, Originality, Production, Tilt, and Vocals. I take my "personal preference" into account via the Tilt criteria. So, even if I like a band just because
, that is only 1/6 of how an album will be judged. There is always going to be a degree of subjectivity in any review though...even in your video game reviews. Wouldn't you agree?
That sort of applies to every artist though. If there weren't any reviews, interviews, concert reviews etc., they wouldn't gain popularity at such a fast pace. Even Drake and Kanye weren't "legends" from the start.
