the fact that the dance-pop was hardly dominant genre in the United States dawn of the new millennium against teen-pop or hip-hop-flavored R&B styles. McCarthy noticed that Madonna "deftly eschewed the petty cultural battles between genres and generations", and she was seen wearing T-shirts emblazoned with the names of Britney Spears and Kylie Minogue, saying that was her "celebration of other girls in pop music". The author said that "such spontaneous statements of support and admiration are almost boringly common now, but in an era when pop music had been denied entry into the credibility club, the moment held more weight. The Straits Times also noted the year dominated by boybands and pop teen artists, while Madonna ushered 1980s-electro as "a new retro-fad". Silvio Pietroluongo of Billboard called "a move that could be considered either unusual or genius" about the decision of release various formats for its led single "Music" (maxi-CD and vinyl one week, cassette and CD the next). It was described as a "phenomenal week at retail" and that helped push "Music" to the number one at the Billboard Hot 100, giving Madonna her best one-week sales total of the Nielsen SoundScan era for a single at that time with 62,000 units, as Pietroluongo also said: "I'm finding it quite difficult to think of another maxi-CD that has scanned that many units in a week". Track listing All tracks produced by Madonna and Mirwais Ahmadzaï, except where noted. Notes David Torn was not credited on the original liner notes of Music. Madonna added him as a co-writer of "What It Feels Like for a Girl" after she found out Sigsworth had sampled from Torn's 1987 album, Cloud About Mercury, without her knowledge. "What It Feels Like for a Girl" contained a spoken word sample by actress Charlotte Gainsbourg from the 1993 British film The Cement Garden. Personnel Credits adapted from the album's liner notes.
