Pop superstar Beyonce’s second solo album, B’Day, has just entered the Billboard Top 200 best-selling albums chart at #1 with true first week’s sales of 541,196, according to SoundScan. (The pop superstar’s first solo album, 2003’s Grammy-winning Dangerously In Love, also debuted in the #1 slot, with true first week’s sales of 316,846.) The #1 U.S. chart debut of B’Day was mirrored in Japan, where the album rocketed up the international album chart in a record-breaking 2-1/2 days after its worldwide release on September 4, Beyonce’s birthday. The international pop music icon most recently topped around the world with “Deja Vu” (featuring Jay-Z), the first single from B’Day. A bona fide international sensation, “Deja Vu” became the #1 commercial single in Japan and the United Kingdom and achieved #1 Airplay in Hong Kong and Korea. The track made it to #1 on the German Club Charts, became the #1 R&B Airplay song in the Philippines and made it to #1 on major stations in Indonesia. Back in the States, “Deja Vu” peaked at #1 on the Single Sales chart, #1 on the R&B/Hip-Hop Singles chart, and #1 on the R&B/Hip-Hop Singles Sales chart in the United States, according to Billboard. “Deja Vu” was also a #1 song on iTunes.
