You made awesome picks. It's hard to limit with an artist like Elvis. I have a hard time picking my 'favorite' anything because it really depends on my mood and I like such a broad variety of things.
I see @melinda010100 below me. I agree if you get the chance try to check out his movies. They were a bit on the cheesy side as compared to movies now, but something tells me you have an appreciation for cheesy LOL.
