Before I start describing it , lemme tell you that it's the starting theme song in LORD OF WAR
I tried to find that song all over but all were low quality ones .
Here's the name of the song :
For What it's Worth by Buffalo Springfield
It's a 1971 song so I guess that's the main reason I couldn't find it anywhere .
If anybody has it , please upload or there's always the other way as well :P
