I have multiple ones I like
- The Legend of Zelda: Ocarina of Time - The Bolero Of Fire, It's deep, fast-ish pace and at the part where the music gets higher and intensifies, it sends chills down my spine
- Final Fantasy VII - The One Winged Angel boss theme (And the re-make for the movie and for Kingdom Hearts II)
- Guitar Hero: Warriors Of Rock - Best set list any instrumental game has ever had in my opinion, the amount of metal in it almost made my head explode, also it was very difficult to play.
- Rock Band - All 3 of them for the DLC, the amount of metal on there as well along with the RBN (people who make the tracks on their own) The possibilities of finding the song you liked were pretty much 9/10 and I loved it.
