Mariah Carey performed on Saturday Night Live what is rumored to be her second single Migrate from E=MC2. We weren't feeling the song or her live performance. Mariah can really sing and she deserves songs that suit her talent. Mariah Carey fans expect her to deliver substance and not generic tunes. This reminds us of when Mary J. Blige explained how she passed on Umbrella. Umbrella works for Rihanna but Mary J. Blige's fans expect a Mary J song to have a different flavor.
