The same progression continues throughout the song, and the timing is pretty easy 
to pick up just by listening to it.

Intro:
Am C Em G x4

Am             C             Em          G
Spent the last month feeling bad ’bout myself

           Am        C                 Em     G   
I couldn’t speak anything of real hope

        Am               C            Em                  G
And the day came when it hit me like lightning through my veins

         Am           C                Em     G
A sudden change in my groove, in my walk

          Am       C              Em                G
I got my lion heart and electric flowing through my brain

         Am             C              Em    G
Shocking waves make me feel I can float

               Am         C        Em             G
It’s like the city is mine and the dark is my cave

           Am               C           Em
I can’t explain this sudden peace in my walk

           G
I sure hope

[Chorus]
     Am        C       Em         G
I am living my life as if I had powers

      Am      C            Em    G
And tonight I feel immortal

         Am       C           Em    G
I said tonight I feel immortal

  Am       C           Em    G
Tonight I feel immortal

Like I said earlier, the progression continues throughout the rest of the song.
