Rap - Hip-hop tyoe song

Hey ive been loking for this song for bout 2 years now and its absolutly annoying me now. i last heard it bout 4-5 years ago so i only remember little bits of it please help.

What i do remember include

starts of with what sounds like - ya-ya-ya ya-ya, repeatedly

lyrics include (should be accurate, after all been bout 4-5 years) - happy (or lazy) days, come what may - there'll be lots of fun and laughter.

its quite upbeat and hip hop ish.
