When I was 18 I heard AFI's Sing the Sorrow and it completely changed my life. Now I hardly listen to it, but I still credit it with changing my life, because I never wrote poetry until I heard that album. And, once I started writing poetry my style of writing changed, which turned out to change my outlook on almost everything creative. Therefore, Sing the Sorrow changed my life.
I don't care if you love it or hate it, I'm just curious as to what album changed YOUR life (if there was one). It can even be something you hate now, but when you first heard it, it changed you.
Spill! I wanna know.
