If there’s not enough space to put an entire line of lyrics on one line, the rest of the lyrics will be on the following line, but they will be preceded by 4 spaces. This indentation is a reminder that these lyrics belong to the same pair of chords as the line above.

If you see:

There's a fire starting in my heart          [Verse]
Reaching a fever pitch                      Cm Gm
    and it's bringing me out the dark       A# Gm-A#
Finally, I can see you crystal clear
Go ahead and sell me out and I'll lay your shit bare

That means:
