I'm probably not Hippity or Hoppity enough for you, but there is one Creed song..
Ace Of Base - Beautiful Life
Creed - Whats This Life For
Green Day - Good Riddance
The Beatles - A Day In The Life (OK, maybe not)
Eiffel 65 - 03 - Dub in Life (Though I have no idea what this song means probably because I am old.

)
Meat Loaf - Life Is A Lemon And I Want My Money Back (Probably not appropriate)
Monty Python: The Galaxy Song
Monty Python - Bright Side Of Life
Social Distortion - Story of My Life
Billy Joel: River of Dreams (Probably way to mellow)
There are a bunch of more mellow ones. Maybe some Sinatra?
