Not east to even try to compile this, but I'll give it a go. All five are interchangeable.
1.)
The Who - Who's Next
Song after song, this album just comes at you and finishes with one of the great songs, Won't Get Fooled Again. Baba O'Riley, My Wife, Bargain, Behind Blue Eyes, The Song is Over, and more. Wow.
2.)
U2 - Achtung Baby
U2 reinvented themselves, changed their images, and launched a massive tour that did a 180 from where they had been previously. But the album is full of great songs and a somewhat cohesive narrative that focuses on both physical and spiritual infidelity. And how could you resist Oscar Wilde's Salome being retold as Mysterious Ways? You depart Zoo Station for a wild trip. What most don't know is that the repeating guitar sound at the beginning of Even Better Than The Real Thing is an imitation of the sound made when trains in Berlin leave Zoo Station.
3.)
Fleetwood Mac - Rumours
Another heavy hitter that captured all the breakups, despair - everything going on in the band at the time. Once again, song after song hammers you and each of them sounds catchy too. An interesting blend of the battles between Stevie Nicks and Lindsey Buckingham mixed with Christine McVie's more optimistic outlook despite problems in the past and in the here and now.
4.)
Bob Dylan - Street Legal
I'm eschewing traditional wisdom here. I love the bulk of Dylan's work and there are other albums greater, but I think Street Legal is heavily underrated. The word play is great, as usual, and the band arrangements are changed up again. It's hard to pick just one Dylan album in any list, but I have a special place in my heart for this one. This is really where Bob's apocalyptic period started - a period he's been in ever since. The end is looming as he wanders under the red skies and the album opens up with an apocalyptic number and seems to end with a conversion. It's that soft spot in my heart that made me put it here over Freewheelin' Bob Dylan, Another Side of Bob Dylan, Bringing It All Back Home, Highway 61 Revisted, Blonde on Blonde, John Wesley Harding, Nashville Skyline, Blood On The Tracks, Desire, Slow Train Coming, Saved, Oh Mercy, Time Out Of Mind, "Love and Theft", Modern Times, and Together Through Life. Any one of those albums is deserving.
And this is the album iTunes tells me I've played more than any other and I've got six years of history logged in iTunes. So maybe I should've stuck it at #1.
5.)
The Beatles - Abbey Road
Hard to pick between Beatles albums, but Abbey Road is my favorite. George contributes two of the best songs The Beatles ever did. The suite on Side B is just great, combining snippets of songs John and Paul were working on. And closing Side A with I Want You (She's So Heavy) and its jolting, sudden end is genius when you consider the flip over to Here Comes The Sun. That song never fails to make me smile - beautiful.
Other Beatles albums are also deserving. Revolver, Rubber Soul, Hard Day's Night, and Sergeant Pepper. The White Album is a bit too spotty, though it rises to great heights.
Honorable Mentions:Rolling Stones - Beggar's Banquet, Let It Bleed, Sticky Fingers, Exile On Main Street.
R.E.M. - Murmur, Reckoning, Life's Rich Pageant, Fables Of The Reconstruction, Document, Automatic For The People, Monster, New Adventures In Hi-Fi.
Springsteen - The Wild, The Innocent, and The E-Street Shuffle, Born to Run, Darkness on the Edge of Town, Nebraska.
Pink Floyd - Animals, Wish You Were Here, The Wall (Dark Side Of The Moon is soooooo overrated).
The Who - Sell Out, Quadrophenia.
U2 - Boy, War, The Unforgettable Fire, The Joshua Tree, Zooropa, All That You Can't Leave Behind, How To Dismantle An Atomic Bomb, No Line On The Horizon.
Peter Gabriel - Peter Gabriel 3 (Melt), Security, US, Up.
Genesis - Selling England By The Pound, The Lamb Lies Down on Broadway, Trick Of The Tail.
Beach Boys - Pet Sounds.
Brian Wilson - Smile.
And plenty more that I can't think of.
