Greatest soundtrack? Easily Megaman 2, almost ALL of those songs are classics. Then Zelda Ocarina of Time. And that's a fact.

FF7 and X are amazing but I'm just going to go fanboy and say Halo

Wind Waker soundtrack beats Ocarina, sorry guys. Still the best Zelda soundtrack.

Can't speak for all-time greatest. I suppose I'd say either Mario Galaxy or Xenoblade had the best OST on Wii. Picking a Smash Bros game feels like cheating, especially for Brawl and 4 where half the tracks are ripped directly from the source material rather than remixed (not that I mind).

Best OST on 3DS is still Kid Icarus in my opinion, but dammit does Bravely Default make this a hard choice. For DS I'd probably go with a Pokemon game. Black 2/White 2, I suppose. GameBoy - Link's Awakening, GBC - Oracle of Ages, GBA - maybe one of the many Mega Man games?

For the NES I'll go with Mega Man 2, for the SNES I'll pick F-Zero, N64 Ocarina, GameCube Wind Waker. Best soundtrack on Wii U so far is Shovel Knight.

Journey really deserved its Grammy nod, that music is fantastic.
