Bittersweet penny

Million things to say, million brains to waste
million my mistakes, million things never change
millions make you talk, millions make you walk
millions heal your pain, millions and a life can change
Within your life, can't live without 'em
within your mind, you're addicted
Can't exchange a coin for life
When you're feeling sick, when you need a brick
to wash away a stain, or if there's something in your brain
the need to change a gear, or maybe disappear
just only for a beer, money! and everything is clear
Within your life, can't live without 'em
within your mind, you're addicted
Can't exchange a coin for life
