ROTF. Endless Love is one of the best ever vocals. If you think its a screamfest go listen to Rihanna or something. Mariah was never here for restrained boring vocals.
Anyway @Kevo, yeah Merry Xmas was her best album vocally for me. She took it to church on every song and the production on the songs was also very impressive. It showcased the fact that she can stand out as one of the all time vocal greats and sing classic songs BETTER than anyone else. I personally found Memoirs to be so underwhelming and tired that I for one cannot wait for this change of direction.
