seeking recommendations for melodic , ear pleasing, and musical sounding LP's?

On a reasonably resolving home audio system, sound of a piano can be quite expressive and musical. One example is Holly Bowling’s interpretations of Grateful Dead music on “Better Left Unsung”.

Soundtrack from Inside Llewelyn Davis. Great movie too. 

I've always thought the "Love Over Gold" and "Brothers In Arms" releases by Dire Straits were superb sounding.

Another way to go is to invest in the "The Wonderful Sounds of..." series from Analogue Productions. They have "The Wonderful Sounds of Female Vocals," "The Wonderful Sounds of Male Vocals," The Wonderful Sounds of Christmas" and "The Wonderful Sounds of Quality Pressings." On my system, most of these cuts sound, well, wonderful. Rich, beautiful recordings of what I think of as interesting music. I'm sure you will hear many things that you enjoy. And then you can seek out the albums from which those cuts came. 

Good luck,

David

Dire Straits for sure, but also later Steely Dan releases. I'd also check out Miles Davis "Kind of Blue", Charles Mingus "Ah Um", and Return to Forever "Medieval Warrior".
