I tend to notice that most people like the greatest percentage of music around when they were teenagers and/or young 20 somethings. I think sad is about 10 years my junior and his feelings of 70s music jive with my feelings of 60s music.
This of course is not a scientific observation just my observations on the subject.
That's about right, and many studies back that up. I'd say that about half of us here on DRC still listen to new music - me, sadchild, Hectic, Jon, Monostereo, perhaps others. But I think we'd all agree that the passion we have for the music from the formative years of our lives, goes beyond the music we like in our later years. Old Chicago, Yes, Doobie Brothers, Steely Dan, J. Geils Band, B-52s, Cars, Springsteen all generate stronger emotions for me than Radiohead, Black Keys, Courtney Barnett, Tame Impala, or St. Vincent.
Although I must say, I have a period during my adulthood, where certain music has given me a big emotional hit; Aimee Mann, Pearl Jam, PJ Harvey, Smashing Pumpkins, Alanis Morrissette. But as we've discussed here before, some of us treat music just like TV and movies. While I'll always cherish my memories of MASH, All in the Family, The Odd Couple, and Sanford and Son; I couldn't imagine giving up on TV, and skipping Seinfeld, Sopranos, The Office, Six Feet Under, or even The White Lotus. And for me, I'll always seek-out and enjoy new music, like I do with TV.
