The Fallout Soundtrack. Specifically New Vegas. And one song, in particular, always has grabbed me and makes me think of the game.
*snaps his fingers*
Oh yea, time to get to some bandit killing and raiding the wasteland.
Truth be told the Fallout series has always had fantastic music, and with Fallout 4 coming tomorrow, I cannot wait to hear the soundtrack. Having my PipBoy play this stuff while I hunt and pick through the wastes always sets the perfect tone.
Ring a ding ding baby!
