Impossible task. I guess Rumors or one of the Beatles albums, but CNSY is very listenable as well. No one is mentioning more current music for this generation; I would guess TS would be on their lists,
Better would be picking 12-14 individual songs to make one "album" of favs that would be more listenable over time. I would have one side of rockers and one side of slower tunes. That way, you could mix jazz, rock, classical, etc.
Cheers!
