Personally I fell like destiny has the best soundtrack of any game in its style (Fps RPG). The only thing that may go beyond it may be halo in my opinion.
Some of you may think the game sucks and while it is flawed, no game is ever perfect. But I feel like Destiny's soundtrack is one huge redeeming quality. You have Shadow Thief (best soundtrack for a fallen trailer), surge of light (which plays during the subclass quests and is awesome) and the Warmind (otherwise known as a the vanilla soundtrack) and more.
Bungie if you read this. Don't stop making badass soundtrack and sounds.
