Wow, tough one to answer. There are so many great Albums out there and the older you are, the more selections you have to choose from.
My favorites come from deferent eras so I will list but in no certain order.
The Wall-Michael Jackson
The Long Run- The Eagles
Come On Over-Shania Twain
The Complete Collection-Garth Brooks
And there are so many others I could add, but these 5 top my mind instantly.
