Yes, before it begins: people still buy CDs. They make great gifts and actually sound BETTER than an MP3. I think CD sales may actually still make more $$$ than downloads for the industry. I know for artists I collect, I still buy the CD. Amazon may have saved the compact disc with this innovation!
I think there are several demographic groups consuming music now.
The younger crowd is all mp3 all the time wherever they can get it as free as possible.
Collectors who want the "hard copy" of the music they like
Old geezers, (like me) who went through buying LP's (have over 600, I don't know what to do with), converting their stuff to CD's and are now only listening to music as background in the car or while working.
Most of the time I now listen to satellite or talk radio and want funny stuff.
The latest hits meh, One Direction (Yes, only direction is go down fast), Justin Bieber (uurrgh)
Being 60 and Stuck in the 60's and loving it. Trying to get rid of all material possessions too.
So, mp3's on my iphone or MBP are perfect. Don't claim to have a good enough ears to hear the differences between formats.
PS: My kids have been discovering my music ever since they were 12 and like it better than what is around now (With a few exceptions)
Go Sirius XM for old-timers.
