Dre's verse was written by Ross, I don't see how there could be any debate on that. This is a pretty mediocre track. Dre's reciting way too hard for a track this laid back. Ross...is Ross. More of the same saying nothing raps. Jay did his thing for what was most likely a phoned in verse.
Been hoppin out the BM with your bm
takin her places you can't go with your per diem
screamin carpe diem until I'm a dead poet
Robin Williams shyt I deserve a Golden Globe bytch
Besides flowing impecabbly:
Edit:
@Nas stans: people liking Jay's verse doesn't take anything away from Life is Good. Stop being insecure little bytchmade fakkits.
