Not counting some of the 90's stuff I listened to in elementary school, pretty much everything I loved prior to turning 30 has held up into my mid-30's (or I guess late 30's- will be 38 on Xmas yikes). There are certain things I don't really listen to anymore but I do go through phases of revisiting old stuff and my opinion is usually the same, or at least my objective opinion is. And there are of course some artists like VU and The Stones who I always liked but have grown to appreciate more with age.
Agreed re: the "Wall" film making the album redundant. Don't forget to watch it BLUNTED brahski!
