The Opening and Ending for Angel Beats! is simply epic. You start with a booming, awesome, piano solo in the opening and end with a relaxing song at the end.
Also, Clannad's ending, Big Dango Family, bro. Lol

anything ALI PROJECT, but must say code geass ED 1 is my fav
My favourite always changes, but at the moment, my favourite opening is 'sky's the limit' from Persona 4 The Animation, and my favourite OSTs are anything by Yuki Kajiura and the Black Rock Shooter OST~
