3 Doors Down is my favorite band of all time. They have a ton of songs that I literally love, so this is a really hard pick for me. I've been thinking of picking "Kryptonite, Here without you, Loser, Down Poison" or even "Give it to me". But I'm going to go with "When I'm gone" I love this song so much. It has powerfull lyrics and a awesome beat. I really love listening to it when I'm running just so I'll get a extra bit of motivation. "When I'm Gone" is one of the few songs that I never get tired of. That makes it 3 Doors Down's best song IMO.
