I'm having the Mariah fever lately. Can't stop listening to her music or watching her videos, or searching the internet about her. It's crazy. The last time I had that with her was in 2005 when I started being a fan of her music.
I think all of her Eras are perfect the way they are. There is always room for improvement, but all in all, I'm very satisfied with how her career is handled. Memoirs was a mess, but Obsessed, IWTKWLI and HATEU were the only possible single choices in my opinion.
