Cover art for Good For You lyrics by Marianas Trench

LOL it's called "good to you" not "good for you"

"But I still have your letter, to stock up between.?" is "and I still have your letter , just got caught in between" and after "Someone I just invented, and who I am really am" it goes "and who i've become"

and it's "i can't be without" not "You bring me higher."

i think this is about a couple in a relationship and they are saying to each other how they'd be so good for each other and they would make everything right. but then again, josh probably wrote this not intending it to be a duet, so it might not be about a relationship, just one person. =)
