Found another: "Come On In" by Holley Gray, Richard Preston, and Ben Greenslade-Stanton [Perfect Pitch].
EDIT: Also, I've made a correction. "Cuba Libre" by Wicked Ear Candy is the wrong track; it's actually "Autlan Heroi" by Coco Pop [Funky Junkies], though in fairness the two tracks are extremely close.
EDIT 2: Another ID: "Crazy & Cheeky Boogie Sax" by Glenn Cartier and Valentin Pagani [CosMind], which plays in many episodes.
