Hi Darin -
Without knowing what you have in your collection, it's a bit tricky...
It sounds like you're after something upbeat/happy. A couple of suggestions off the top of my head would be...
Holiday (Green Day)
Holiday (Madonna)
Good Vibrations/California Girls (Beach Boys)
Born to be Wild (Steppenwolf)
We Gotta Get Outa This Place (The Animals)
The Final Countdown (Europe)
I Got You - I Feel Good (James Brown)
Celebration (Kool and the Gang)
If you are into mixing your own soundtrack to capture particular moods, there's a site I use which has a great range of short tracks in every style/feel you could think of. It doesn't have commercial music - like the ones above - but it's easy to search for what you're after & download it (free).
