List of albums that will still be popular 50 years from now...

Tostadosunidos,
Some hip-hop and rap is backed up with great instrumental and funky work!
Speaking of rap 

Bestie Boys -- "Lisence to Ill" has VERY good chance to live 50 years more from now as it's almost lived already half-the term so as albums down bellow:
Public Enemy -- "...Nation of Million..."
Run DMC -- "Raising Hell"

You can't go 1 day in NYC without hearing at least one song from that album on the radio.

*L*  Well....the Beastie Boys got picked for 'Star Trek - Beyond", so it's kinda an open call.  Floyd will likely make the long run.  Dylan might make it with the historians, as might some of the Beatles.  'Ell, predicting the future is subject to the wild guess, Van Halen might make the cut. *LOL*  "Hot for Teacher" opening drum solo reminds me of the idle of a AA fuel dragster; it might be used as an example to a post-petroleum era of what they sounded like, and what we liked to listen to when 'at the drags'.
You could be pro-active about it...burn some CD's with your picks, box them up with a player (Don't forget to add the instructions), and create your own time capsule.  Leave it in a vault of some sort, create a 'do not open until XXXX', and forget about it....
'Course, you won't know what happens unless you include instructions on how to retrieve and reboot your frozen head....;)
I like threads like this....network time wasters, but fun.... 

From the very current bright stars, I'd nominate 

Sona Jobarteh
Melody Gardot
Alison Krauss

Identical to Brittney Spears, that almost faded away, Beyonce, Justin Timberlake and Beiber and other super-popular artists will less likely make it there...

what about Joanna Newsom? It will be funny to see her (and maybe Bon Iver) as icons for the nerds in 2066...
