Ben tweeted a link to SPIN magazine's 125 best albums of the last 25 years. I am unable to comment on the list itself - I mostly clicked through just to see if I recognised any names whatsoever (yeah, a few). But I noticed a similarity to Rolling Stone's Top 500, which I commented on here.
A highly disproportionate percentage of the top 15 were from the earliest years (beginning 1985), as a highly disproportionate percentage of Rolling Stones top picks were from the 1960's. People who write for rock magazines care greatly about firsts, influences, shifts, and fusions. They are much more attuned to durability, and whether that particular branching went anywhere and was copied by others. While one is in the era, just listening to the radio and hearing what's popular, we only care whether we like it. New directions may or may not persist. But those who study like to see patterns develop.
That's my only spoiler. If you click through to SPIN's list, the top 15 are strongly weighten to the 80's and early 90's.
