There are albums by Boston, Rush, Styx, Billy Joel and more that I can still sit and listen to from beginning to end. Yet I haven't actually bought a CD, let alone sit and listen to a whole CD in years. I download individual songs. So what's the difference? Me or the music?
I don't have an answer. I'm just putting it out there.
Some albums I can still listen to from beginning to end:
Boston - self titled
Rush - 2112, Moving Pictures (technically not 70's. Released in 1980)
Billy Joel - 52nd Street
Styx - Crystal Ball, Pieces of Eight (links are not to full albums)
Van Halen - self titled
Fleetwood Mac - Rumours
