lol, it's all subjective. The only OP songs I really like are Hope and Future on the Same Page, and the one from Tearaway. I never did get around to listening to those games' full ost's.
Though I do really enjoy most of Gravity Daze's soundtrack, too. Actually, it's tied with Kid Icarus: Uprising and Bravely Default for my favorite current-gen handheld soundtrack.
