'Sunlight,' the Plain White T's latest single from 2008's 'Big Bad World,' means a lot to bassist and backing vocalist Tim G. Lopez. "For me, it was a desperate song," Lopez says, describing a struggling long-term relationship. "I actually have, I don't know, ten songs about that topic. That one was the only one that ended up being positive." The band decided to film the non-traditional music video themselves, with Lopez talking about the song's personal connection in between live footage from shows and festivals.
