While we get very excited about downloading music, the discussion over DRM and which MP3 player is best, only one in four online consumers have acquired music via digital downloads, according to CEA Market Research in a study called "Uncovering Trends in Digital Lifestyles."

I would have certainly guessed a larger number, particularly since the aisles of stores where CDs are sold are rarely crowded -- and yes, you can get these CDs over the Internet instead.

Perhaps we are now spending more money and time buying DVDs rather than music?

Of course that all could change with the next blockbuster hit.

But will any artist ever hit these sales levels (from the Recording Industry Association of America's Top-Selling Albums of All Time):

• 29 Million: Eagles: Their Greatest Hits, 1971–1975, Eagles (Asylum)
• 27 Million: Thriller, Michael Jackson (Epic)
• 23 Million: Led Zeppelin IV, Led Zeppelin (Atlantic); The Wall, Pink Floyd (Columbia)
• 21 Million: Greatest Hits, Volumes I & II,  Billy Joel (Columbia); Back in Black, AC/DC (Epic)
• 20 Million: Double Live, Garth Brooks (Capitol Nashville); Come On Over, Shania Twain (Mercury Nashville)
