In early 2007, Carey began to work on her eleventh studio album, "E=MC²", in a private villa in Anguilla. Although "E=MC²" was well received by most critics, some of them criticized it for being very similar to the formula used on "The Emancipation of Mimi". Two weeks before the album's release, "Touch My Body", the record's lead single, reached the top position on the "Billboard" Hot 100, becoming Carey's eighteenth number one and making her the solo artist with the most number one singles in United States history, pushing her past Elvis Presley into second place according to the magazine's revised methodology. Carey is second only to The Beatles, who have twenty number-one singles. Additionally, it gave Carey her 79th week atop the Hot 100, tying her with Presley as the artist with the most weeks at number one in the "Billboard" chart history."
