I believe younger people listen to more music than we ever did, but yes, they also do it more casually. There is so much more to distract them than there was when we were their age. Also, if we wanted to listen to music, we pretty much had to sit down and do just that. The alternative was either a little "Transistor Radio" or later, a "Boom Box". Now portable private options are just ubiquitous, and even run of the mill sound, is superior to some decent stuff from back in the day. Even back in the day audiophiles were not every-man, and much of what got people into it back then was the novelty of having audio reproduction in the home, and some of those people strove for more/better, but most were still just as happy with whatever they got at Korvettes or Two Guys...
