My newest contemporary reference is Hand.Cannot.Erase. by Steven Wilson.
For acoustic music, I like New Favorite by Alison Krauss & Union Station.
For classic R&B/Soul done to modern standards, it's Soul by Seal.
For clean pop (I don't know what else to call the genre), I do like Donald Fagan's Nightfly. Also Brothers in Arms by Dire Straits.
Dark Side of the Moon remains the gold standard for classic rock. The first Heart album is another good one.
