I love Silvergun Superman. I've dealt with 'friends' like that who have practically changed who I am and who to trust and that song definitely goes hand in hand with these experiences.
And then that led to Sour Girl... I find that song incredible and a huge step out of STP land, yet you know it's STP. That's the beauty of this band. Also, I know a sour girl because of a silvergun superman...sooo yeah...going with Sour Girl.
