Pink Floyd's The Dark Side of the Moon is 40…

Dark_Side_of_the_MoonEvery year is getting shorter, never seem to find the time.
Plans that either come to naught, or half a page of scribbled lines…

Steve Burnett pointed out on Twitter today that Pink Floyd's The Dark Side of the Moon was released in March of 1973. Forty years, folks!

Given that it was already "classic rock" by the time I discovered it (in 7th or 8th grade, I think – though I'd heard much of it on KSHE already), this makes me feel just a wee bit old.

Despite that, I like the fact that I've been listening to this album for decades, and it still hasn't gotten old. It holds up really, really well. (The same can't be said for all of Pink Floyd's work, of course. I've listened to "Atom Heart Mother," and "Ummagumma" maybe twice in 20+ years.)

What albums from 2013 are likely to be worth listening to in 40 years?
