The Frozen soundtrack has iced an eighth week at the top of the U.S. album chart. No release has spent more time at number one since Adele hit the top spot 24 times with 21 in 2011 and 2012. The soundtrack, which features songs by the movie's stars Idina Menzel and Kristen Bell, has now sold over 1.8 million copies in America. Shakira debuted her self-titled album at two with 84,000 first-week sales, and late country legend Johnny Cash returned to the chart at three with Out Among the Stars, an album that was originally scheduled for release in 1984. It's Cash's sixth top 10 album. Rockers Memphis May Fire's Unconditional entered at four and Pharrell Williams' G I R L climbed back into the top five at five. Williams also ruled the Billboard Hot 100 singles countdown for a sixth week with Happy. The feat helps the hitmaker jump ahead of Elvis Presley among male artists with the most weeks at number one in the chart's 55-year history - his four chart-toppers have kept him at number one for a combined 23 weeks; one more than Presley. Williams now ties 50 Cent and Nelly for 10th place among men with the most weeks at number one. Usher leads all solo males with 47 weeks at the top, while Mariah Carey leads all artists with 79 - 20 more than The Beatles and 26 more than Rihanna. Meanwhile, John Legend's All of Me stayed put at two on the new chart and Katy Perry's Dark Horse held steady at three.
