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

The Beatles music in general in my opinion is timeless. The list of Rock/pop artists that were influenced by them is nearly endless.
Their music will probably be around forever😎

Thanks tostadosundios , I shot my self in the food with the wrong wording . One word equals a big difference . Got the lecture from my guitar playing brother too . I'm really enjoying this topic . I subscribe to Tidal and am able to listen to everybody's suggestions . So thanks to everybody for their suggestions . The only problem I've encountered is that I went to low power tubes and a lot of the old rock is poorly mixed and sounds poor . Oh well , Regards , Mike.

@oregonpapa and @sevs, 
I was under the same impression, but if all of a sudden Russian balalaika and bayan melodies will be main interest Putin, it definitely does not mean that I have to trash all of these records and stop listening to them.
Same way Wagner did not intend to write music for Third Reich in late 19th century, but was idolized by Nazis as true Arian German composer.  

I think Alvin and the Chipmunks will experience a resurgence.

PS: Please help me. Who are Putler and Killery?
