This would be my song when I came into the game as a closer; get ready for this; make sure you Youtube it; this song, first 60 seconds, would scare the bejesus out of any hitter, and probably scare the women and children in the stands, too.
Knife in the Dark composed by Howard Shore.
(Lord of the Rings Soundtrack)
Seriously, Youtube the song.
Wait, I will just do it.
