Bruce Cockburn-"Anything, Anytime, Anywhere, Singles 1979-2002"
This album contains "Wondering Where the Lions Are", "Lovers In a Dangerous Time", "If I Had a Rocket Launcher", and "A Dream Like Mine" all on the same album, plus 12 others. The CD that I have includes a bonus CD of Live material. Great intro to Bruce Cockburn, if you’re not already a fam.

If I go back to the 70’s, an obscure LP that is great “ease into the day” music (or possibly hookah bar happy hour) is Sopwith Camel; The Miraculous Hump Returns from the Moon. Hard to describe but enjoyably cool at first listen and repeatedly so.
 Captain Beefheart; Clear Spot. 
Shawn Phillips; Second Contribution
 Bobby Blue  Bland; Dreamer

not obscure but possibly under appreciated Van Morrison; His Band and the Street Choir. 

Wussy -- Attica

James Gang Miami. Dated, but fun in a 70's way.
