Lyric discussion by brodiebankyaz

The last part should be:

From now on, I'm someone different 'Cause it's no fun to be predictably lame From now on, there's true indifference 'Cause I just want what I want

brodiebankyaz is right about the final stanza.

That's such a heartbreaking line

"From now on, there's true indifference 'Cause I just want what I want"

It's like "I'm totally apathetic because I want something and I know I can't have it"
