FLATLINER intro/verses: C D C C D C Chorus: F G Am F G Am F C G Am F G Am These are the correct chords for sure but i think that there are a few more power chords in there towards the end. I dont know all the lyrics so i just didnt down at all. Butthis is pretty much all the chords and there might be some lead in there but im not sure. HAVE FUN!
