According to the data, the biggest selling album of the year was Chris Daughtry's "Daughtry," which has sold 1.7 million discs. For digital distribution, Gwen Stefani's "Sweet Escape" was tops with 1.8 million tracks sold so far.
Analysts stated the obvious when trying to explain the surge of digital sales compared to physical CDs. They attributed the numbers to the popularity of MP3 players especially the iPod and to the new focus of the music industry on hit singles. Consumers are much more likely to buy a track they know and like then buy the whole CD.
