Allmusic is pretty good also in regards to their review and album ratings too. Another good site is sputnikmusic.com. It is a user based site that it biggest feature is its rating system. Users can rate band albums on a scale of 1-5 with 5 being classic. As well users can write reviews of each album and others can vote on said reviews to be the featured review for each album. The rating system is pretty damn good and I've noticed a lot of the music I listen to the ratings for the albums are in par with what I would rate plus I've found some bands I'd otherwise not known about on that site.My go-to has always been allmusic.com. Type a band you like and look at the "Influenced By" and "Similar Artists" tabs. Allmusic usually has a "Album Pick" which they consider the artist's best album so from there, I just load that up on YouTube and check them out.
They are really spot on and have led me to a lot of good new bands.
Is last.fm still a thing?
