Cover art for Mountain lyrics by Good Charlotte

To "neonlovechick", I believe the line "i wasn't on a mountain when it came to me" is a way of saying they started from the bottom, and inspiration came from their own lives as they lived them, rather than sitting on a mountain contemplating lifes issues.

They are saying their songs come from around them and what they've been through.

To "oleander", i'm pretty sure "I'd give up all these dreams to have you in my arms right now" is them saying, although they are a famous band and they have, allegedly, everything, they would give up all the fame if it meant they could be with the one they love.
