Especially considering that album dropped when I was 10, and a few years before I even got into hip hop, the fact that it still sounds ahead of the current time speaks volumes. ATLiens not as much, but definitely not dated.

Second cosign on Mos' Black on Both Sides, but BDP and PR/CL albums sound dated to me, the former more so than the latter. But, I think it's easier to gauge what's dated and what isn't when you're someone who is hearing these albums after the fact. An album you grew up with and loved may sound fresh and not dated to you even though if a brand new listener were to pick it up they'd be able to tell that it's decades old.
