In answer to this...
One note of caution: If an album has only 1 or 2 songs on it that I like then... I may like the artist/ songs but don't care for the album. I've never listened to the whole album by Bill Withers, Joni Mitchell, Marvin Gaye, some others... but I do know that I like a song or two. In either case, I wouldn't rank the album as I'm thinking in terms of loving the album, not just 1 or 2 songs. Aside from that:
Genesis was too much for me at that time period. I liked them more after Peter Gabriel left and they became a lot more pop, or easy to listen to. Now I really love me some Peter Gabriel... but not with Genesis.
The Rolling Stones/ David Bowie/ Pink Floyd/ have better albums than these, but there's at least one or two songs I like per album. Same with Bill Withers & Marvin Gaye, there's 1 or 2 songs that I absolutely love, but I can't speak to the whole album as I haven't listened. The Allman Brothers I know the whole album, but mostly just care about 1 song. None of these albums would gain a ranking from me... just not enough there when I'm thinking in terms of albums.
As an entire album, these are the ones that are historically great, I love them to death, equally. I can't put any one above or below the other:
Led Zep IV, Who's Next, L.A. Woman.
These others, I absolutely love the album, even if they are not as iconic as the above albums (so they get the smaller font). I wouldn't be able to separate them or rank them, just as above, as I love each of them for their own uniqueness in sound and mood and excellence, but they are 1 step below the above list:
Fragile, RAM, Imagine, Masters of Reality, Aqualung.
