There is no way on this earth that I can choose ONE album, however, I can give you a list of a few iconic albums and why I LOVE them :
Sounds of Blackness The Evolution of Gospel completely blew the lid off of traditional gospel and broadened it to a wider audience I was a “church girl” struggling with the rules and regulations, I felt restricted but on the other hand I was enjoying working at Choice FM BIG TIME ….. and then this album lands on my door step. The first interlude is “Chains” I saw that as a sign to free myself from chains and being anchored down. The next track is “Optimistic” … you can win as long as you keep your head to the Sky 
Michael Jackson Off The Wall
Still remember hearing Don’t Stop Till You Get Enough for the first time
it was fire –
Michael Jackson went quiet for awhile in fact the last song I remember all six Jacksons boys performing together was Destiny
Then Michael comes out Off The Wall.
It was fire 
Marvin Gaye Let’s Get It On the album track has the 2nd verse that’s rarely played if at all on radio. I think the passion increases in Marvin’s voice on the 2nd verse. Added to that I love doing a little Two Step on the track “Come Get To This”
Blackstreet’s Another Level
Played this album non-stop during the height of the R’n’B era (Good Lovin)
Love Love Love Teddy Riley.
That track “Before I Let You Go” …. Turn on the air conditioning
When the album “Another Level” dropped my first memory was having a cup of hot chocolate before I went to bed (I was doing Breakfast on Choice FM) and listening to that album and I could not sleep:
The interludes
No Diggity
If You Need A Fix
Good Lovin
Let’s Stay In Love (no holding back emotions)
Gonna Take You Back interlude into Don’t Leave (lawd …… Tupac uses the sand sample I in “I Ain’t Mad At Cha”)
I Wanna Be Your Man
The true musical genius came out with their spin on The Beatles “Money Can’t Buy Me Love” 
I could go on but they end the album on The Lord Is Real …… took me right back to The Sounds of Blackness
Carole King Tapestry
Without this album they’d be no Natural Woman by Aretha 
If Carole King hadn’t written, produced and recorded the album they’d be no
It’s Too Late
Will You Still Love Me Tomorrow
You’ve Got A Friend
But more importantly THIS would have never happened
