Summer Happiness Mix

I'm loving the current sunny weather in Winnipeg, and as such it has inspired me to make a happy summer mix, comprised entirely of songs that are like a musical ear-to-ear smile. What are the songs that make you the happiest when you hear them? Here's some obvious choices I've got so far: 1. Martin Sexton - Happy (from Seeds) [bonus - here's a making of Happy video from Martin in the studio] 2. Ron Sexsmith - Happiness (from Retriever) 3. Rufus Wainwright - California (from Poses) 4. Amos Lee - Bottom of the Barrel (from Amos Lee) 5. Jenny Lewis featuring Elvis Costello - Carpetbaggers (from Acid Tongue) And now it's your turn to help me out ... input, please!
