Real good points @mustbethemusic. Very few people these days just sit and listen to music, as a destination activity. Many people just like a particular song by any given entertainer (as opposed to artist ;-), and are not necessarily interested in the album that song is on.
I have spent much of the leisure time in my life listening intently to music, as I believe have many others here. For us, a good system is a worthwhile investment, as it provides deeper immersion into music. For those to whom music is not as important, a good system is not necessary.
There ARE young people really into music---I saw a bunch of them looking through the LP racks at Music Millennium in Portland yesterday. I found a new/unopened copy of Lucinda Williams' 2011 album Blessed, the limited edition deluxe version, sale priced at $19.99. The CD floor was almost deserted!
