I need a good song to animate a fight too, but all the songs I find have an annoyingly massive build up and the main music isn't fast enough. Anyone know any good ones?
I would check out Swordland from SAO. It has the same amount of buildup you would find any soundtrack these days. If you want to tell a little narrative then this is the one.
You can also check out Heist by Lindsey Stirling. This would probably be better if you want to just have an action scene.
