Really?? Again?! It's all a matter of taste. These are opinions, not facts.
Can't Let Go is one of my favorite Mariah songs of all-time. Emotions is great, and I enjoy The Wind and If It's Over sometimes. Overall, though, I like more tracks on E=MC2. The same goes for Music Box: AYNAF and Dreamlover are amazing, but the rest of the record isn't that great.
In my opinion, Mariah has made five stellar albums from start to finish that i find impossible to rank: Mariah Carey, Daydream, Butterfly, TEOM, and Memoirs. E=MC2 would be my sixth, just because I'm not completely enamored with any song in particular, but I still think it's a more solid effort as a whole than Emotions. I don't know where the rest would fall, but CB would probably be last.
Nobody here is hating. You can love an artist without loving all of their output. Sh*t, Mariah doesn't even like a good majority of her back catalog on Sony.
