Recent research from the NPD Group shows that Apple’s iTunes Music Store is the seventh largest music retailer in the United States, notes Macworld UK. “The iTunes Music Store beat out Tower Records, Sam Goody and Borders in NPD’s third quarter ranking to crack the top ten for the first time ever, the research claimed. iTunes’ fast ascension to seventh place reflects the speed at which users are turning to music online,” notes the story. NPD Group ranked the iTunes Music Store against traditional retailers by counting 12 songs per album to compare online sales with physical CDs and singles.
