Welcome to MB, Simon S :wavey: You've started with a great idea - you should stick around.

Totally times two for Psy-Fi's picks of Dancing in the Street, Be My Baby and Good Vibrations.
Here are a couple from me:

Daydream by The Loving Spoonful
Then He Kissed Me by The Crystals
Take The Money And Run by The Steve Miller Band
Good Day Sunshine by The Beatles
Spirit In The Sky by Norman Greenbaum
On The Road Again by Canned Heat

Plus two lesser known songs:-





My list is longer than I expected, because like goldendoodle, I don't want to be TOO happy. That's why my list has so few Brits on it; we don't do Happy; we do dreary hardship in a bad climate for convoluted reasons that stem from economic downturn, post-war guilt, medieval religious masochism and Spartan Victorian values.

More (because for some reason I was only thinking of more mainstream/current pop stuff before)

Awesome. This looks like a fancier (and better sounding), antique version of the traditional Dutch barrel organ. They don't play contemporary pop music that often (unfortunately), but this brings back fond childhood memories

This one might be the ultimate "feel good" song...
