Lately it's been Joni Mitchel's Both Sides Now. Great arrangements, tunes, transparent recording, mellow voice, in the words of Larry Kart's great phrase of about a week or so ago, "not cheap" (thanks for that one, Larry, lot of meat on that bone, for real) about an hour long, perfect for laying down, drifting off, snoozing a tad, drifting back in, waking up physically rested, mentally refreshed, and musically pleased.
