Any of you HHCers out there know which song this is?

I'll be happy till the day I die, I smile each day and I don't ever cry...
Feeling sad is such a waste of time, so just be happy... just try...

Every time I hear it... I just get infectiously bouncy and happy-twitchy. :-) But it's always something like 'DJ SoAndSo, Set 437' for the streaming radio ID of the song. =-.-=
