I give the seal of high approval to the following albums. It has some variety, a bit of classic rock, some more contemporary stuff but I'm mostly very into acoustic, folk-pop kind of musical stylings. 
U2 - The Joshua Tree (and everything else)
Peter Gabriel - So
Tom Petty - Full Moon Fever 
Queen - anything 
Fleetwood Mac - Rumors 
Jewel - Piece of You 
Colbie Caillat - Coco 
Missy Higgins - On A Clear Night and The Sound of White 
Lisa Mitchell - Wonder 
Joe Purdy - Only Four Seasons 
Johnny Lang - Long Time Coming 
Gordon Lightfoot - anything 
Joshua Bartholomew* - Joshua Bartholomew EP, And So It Begins, Heart Headed EP 
Sarah McLachlan - Fumbling Towards Ecstasy and Afterglow specifically but anything really 
Bright Eyes - I'm Wide Awake, Its Morning 
Sufjan Stevens - Seven Swans 
Justin Nozuka - Holly 
Shania Twain - Come On Over 
Alexander Rybak - Fairytales 
The Kooks - Inside In The Inside Out 
The Tragically Hip - anything 
Lifehouse - No Name Face 
Silverchair - Neon Ballroom 
I'll stop there for now, I could go on for a while.
