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

Dire Straits second album is, to my mind, superior musically. Not yet over-complicated and overproduced, with superb attention to sound. They still sound like band.

Steely Dan's Aja sounds good, Gaucho sounds good but bright, but when they got to Two Against Nature & Everything Must Go they really accomplished both clarity and relaxed musicality. Same is true with Kamakiriad, Morph, and Sunken Condos. 

A lot of people remember Gaucho and Nightfly as playing nearly continuously as audio showstoppers. IMO, as of today, they're far inferior to the later albums, sonically.

If I guessed part of your system you will want to avoid hot recordings and focus on ones that are tonally deep and warm... with music that is very... up tempo (?). I'm thinking swing might be really compelling for you. 

The Atomic Mr. Basie – Count Basie
