Guess you can never get tired of hearing OutKast's ''Hey Ya!'' That's the best explanation for the success of ''NOW That's What I Call Music! Vol. 16,'' which saw the best sales week in three years for any of the ''NOW'' volumes. Apparently, listeners are also not sick of D12's ''My Band,'' Hoobastank's ''The Reason,'' and 17 other seemingly ubiquitous tunes that make up the hits collection, which sold 550,000 copies out of the box this week, according to SoundScan. That was enough to debut on top of the Billboard album chart, dethroning last week's chart champ, Ashlee Simpson. Her ''Autobiography'' slips to No. 2 in its second week, with sales sliding by one-third down to 270,000.
''NOW... Vol. 16'' also outsold three new releases that entered the chart in the top 10. ''Where You Want to Be,'' the second album by rockers Taking Back Sunday, debuted in third place with sales of 163,000. ''True Story,'' by Fat Joe's rap crew Terror Squad, entered the chart at No. 7. Right behind, at No. 8, was the new self-titled album by Kevin Lyttle, who becomes the first soca singer to crack the Billboard top 10.
Down two spots this week was Jimmy Buffett's ''License to Chill'' (No. 4) which sold another 117,000 copies. Usher's ''Confessions'' slid one slot to fifth place and shifted another 107,000 units. Also down one notch, to No. 6, was Gretchen Wilson's ''Here for the Party.'' Dropping three rungs to No. 9 was Lloyd Banks' ''The Hunger for More.'' Big & Rich's ''Horse of a Different Color'' dipped one position to 10th place.
