There are two albums that I have been listening to regularly for the past 20 years. Outside of the Beatles, that I was introduced to much younger, they are the two most played albums in my collection.
I love them. I never get tired of them.
Union by Toni Childs
I was introduced this one by a friend of my father, and listened to it over and over for months after.

Ghost of a Dog by Edie Brickell & The New Bohemians
This I discovered in my dad's collection while on summer vacation. Again, I listened to it many times per day during the weeks that I had access, and then called to beg him for a copy.
