DL- I also am one who still doesn't own an Ipod. Most of my favorites around the house are still on Vinyl.
My favorite song of all time is "For What it's Worth", by Buffalo Springfield (most of the Crosby, Stills, Nash & Young crew. all their music displays their incredible harmony). #2 on my list is "People are Strange" by The Doors (everything else they did is great also).
Love song; there is no other: "Time in a Bottle", Jim Croce
For headphone, just sitting back and Groovin' music, I strongly recommend anything and everything by Emerson, Lake & Palmer. Probably their most recognized single is "Lucky Man". Along the sames line of music (lots of instrumental, synthecized stuff) are the groups Kansas and Yes. the "YesSongs" albumn is tremendous. And speaking of Groovin', The Young Rascals, best version ever of "Mustang Sally".
I've always been a big fan of Joe Walsh, but I think even better than The Eagles, was his music with The James Gang. "Funk #49" has to be one of the all time best.
For easy listening, I really enjoy my fellow Okie, Lean Russel, "Tight Rope", "Give Peace a Chance". "Mad Dogs & Englishmen", "Wild Horses"..............
And, of course, no collection is complete without All of Eric Clapton's groups (my favorite, Delany, Bonnie and Friends), Pink Floyd, The Alman Brothers, Jimi Hendrix, The Animals, Deep Purple, Procol Harum, Jefferson Airplane, Vanilla Fudge, Edgar Winter, ZZ Top, Bad Company, Steve Miller Band,.....................................gosh, I can't stop.
Simply put; anything recorded between 1965 and 1974
