It doesn’t seem right but Mariah Carey recently notched her 18th No.1 single, “Touch My Body,” and moved past Elvis Presley into second place for most No.1 hits in music history. Carey, who is looking and sounding better than ever (did you see her on “Saturday Night Live?”), stands only behind The Beatles, who had 20 No. 1s. “Touch My Body” is the first single from “EMC2,” Carey’s latest album due April 15. Are there more No. 1 hits on “EMC2?” Let’s see.
