Black Eyed Peas 'I Gotta Feeling'
check out the flash mob dance version on youtube, totally amazing
20,000 people of all ages dancing in unison down Michigan Avenue, Chicargo
I can't link as I'm too new here but if you google
'Maior Flash Mob Black Eyed Peas - I Gotta Feeling, youtube' you'll find it
watching it always puts me in a better mood
