Song In My Head

I think the music video has something to do with relationships. The singer mentions 'everything was new and less watered down before the summer turned to brown' .. and the band members all start out with brown - wearing brown, brown instruments, etc. But eventually the little kid meets up with one of his friends (the girl) and their relationship is young and carefree (shown by the change of brown to pink). That's my take on it.. something like that. :P
