Some good ones already mentioned. A few odd ones that I used over the years. Pink Floyd Dogs
Depeche Mode Personal Jesus acoustic version
John Hiatt Feels Like Rain
Any drums recorded in the front hallway at Headly Grange . The best sound not recorded by John Bonham may be can’t get enough from bad Company’s debut record
Whenever I make a significant change I play Dave Brubeck & Tony Bennett live performance for president Kennedy in 1962. It touches all the bases. You are there, wonderful recording.
Grace Jones -Slave to the Rhythm 
Eagles - Hotel California (Hell freezes over Album).
Queen - Bohemian Rhapsody
