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

I just hope the vastly over-rated Sgt. Pepper album will be forgotten, and the justifiably highly-rated Pet Sounds will endure with current and future listeners.

Hey Czarivey - Just something to think about.  I was actually focused more on singles than whole albums.  Somewhere there's got to be a list of top 100 recordings of all time.  Go through that and see how many date from 50 years back. That would be interesting.  50 years back does put us in the middle of the 60s...a significant time for popular music.  A transition period I would call it. but I'm no musicologist.

I think Mancini is a good call along with Miles.  A couple more names  that I think have enduring appeal are Sinatra (Summer Wind?  Strangers In The Night? or the albums they were on) and any number of R&B performers:  Ray Charles, Aretha,  Stevie Wonder (! Cherie Amour), Temptations (Papa Was A Rolling Stone).  Soul/R&B alone might fill up a big chunk of your 50.  

bdp might be right about The Beatles Sergeant Pepper's BUT I'm thinking McCartney's "Yesterday" will be around, though I'd put Rubber Soul or Revolver ahead of Help!.  Of course, I'm just talking North America/UK markets.  Somebody with a broader world view might have some other thoughts.

sevs - you make an interesting point.  I hung up my scientist hat a while back but I guess you never stop thinking that way...even if unconsciously.  The other realization is how out of touch I am with today's "popular" music.  Outside of some Radiohead and Wilco (MAYBE) not sure much music I like is getting significant airplay.  This made me realize my frame of reference for contemporary popular music is 30-50 years old!  Not that anybody else cares.  Not sure I do, frankly.

I've been teaching pop music on guitar (and other instruments) for over thirty years and I'm amazed that "our" music survived the generation flip.  It boggles my mind that I'm still showing kids how to play Beatles, Cream, Hendrix, etc.  The music is 50 years old.  That said, I had two young sisters in the last ten years who only wanted to play swing and western swing--nothing post-World War II.  They've finally come around to more be-bop flavored stuff.  I was born in the 50's but I love a lot of the jazz and solo delta blues from the 20's, 30's and 40's.  A lot of the best stuff will survive, especially the best known (such as Elvis, the Beatles, Led Zep, Michael Jackson, Nirvana).   I'm not qualified to comment on hip-hop or rap as they are outside of my realm of familiarity/understanding.

Pt. II--If the best known stuff is still heard and appreciated then the question becomes:  which of the lesser stuff survives--the Pixies?  Screaming Jay Hawkins?  Blues Magoos?  Jan and Dean?   We can't know.  You have piqued my curiosity about something that I can never know the answer to (unless I live to be 114).

@ghosthouse : I was thrilled to discover Porcupine Tree because I just "knew" there Must be something similar to PF, like in the 90-ies (only then) I finally "discovered" Electronic Music of TD and KS, by listening to Pink Floyd..  First I just imagined the music, then, through Kitaro I found it! In another 50 years, its a good question how those kids are going to discover Sergeant or Gaucho? Definitely Not by listening to Top 30 ;-)
