Fantastic post and thank you for chiming in with your favorite eras. I think that how your favorite era's list changed over time not only shows your growth and maturity as a person, but it explains Elvis's changing tastes in his music choices as well. As Elvis aged, he was just not going to have the same enthusiasm for most of the early rock 'n' roll stuff that he had as a young man. He was also going to be drawn more heavily to the storylines and sophisticated productions of adult contemporary and county-pop music. Some of his dedicated rock fans would find his changing tastes perplexing as well as disappointing, but it was simply a reflection of age and Elvis's very eclectic taste in music. It drives some fans nuts, and for other fans like me, his broad taste in so many genres of music is what turns us on so much about Elvis's large catalogue.
