The trick to this song is staying on top of the triplets when you're strumming. Some of the chords are “transitions” so listen for the changes. On the C-Cadd9 change, you just drop your pinky down right before the Em. Enjoy!

Everyone thinks I'm a liar No one knows the truth If it was a bigger fire I would be on the roof Ships will rust in Baldwin Bay (Let me go!) No one trusts what I say (I don't know!) Oh my God, no one paid (Attention!) Overnight my hair turned gray (Oh oh oh!) In the end it boils down to credibility I had none, so I will die with the secrets of the sea (Submarine! Can't find me! Submarine!) Submarine... (Submarine!)
