1.Suteki Da Ne (FFX) (Very well put together orchestra parts + I love the japanese language.)
2.Legendary Beast (It's just cool (partly because it plays when fighting griever))
3.Liberi Fatali (great cutscene as well)
4.You're not Alone (same reasons as everyone else that likes this)
5.Eyes on Me (I love FF8)
6.Man with the Machine Gun (best normal battle music in all of FF)
7.Great Warrior (hmm I'll give one to FF7)
8.Dollet Battle Theme (it's just cool)
9.The Oath (same as #5)
10.Battle with Gilgamesh (best song in FF5)

And FF6 lovers, don't flame me just because I didn't choose any songs from FF6, I haven't played that much of it.
