Also, I realize this is a bit of a passe and obvious choice, but I believe in any discussion of perfect albums...
Rod Stewart's 1991 masterwerk "Vagabond Heart" cannot go unmentioned. This is literally a tour de force of 12 straight greatest hits, including the titanic "Rhythm of My Heart", which basically could have been considered the soundtrack to the Gulf War, and the Van Morrison cover "Have I told You Lately That I Love You"
In addition, the track "Rebel Heart", about trying to unwittingly date a lesbian... an expression of everyday life far beyond it's time.
