NPD: iTunes Now #3 Music Retailer

iTunes' dominance in the music industry continues to grow, data from the NPD Group showed Friday. Apple surpassed Amazon as the third largest retailer for music sales in the first quarter of the year, with 9.8 percent of the overall market. Apple is also gaining on leaders Wal-Mart and Best Buy, who finished the quarter with 15.8 and 13.8 of the market, respectively.

Analysts at NPD say Apple's strength is surprised considering sales are down by a fifth over last year. However, they also pointed out that both Wal-Mart and Best Buy are behemoths in the music industry, and will be hard to catch.
