Cover art for Science vs. Romance lyrics by Rilo Kiley

It's called songmeanings.net for a reason, not songappreciation.net. Personally, I think this song has something to do with a long-distance/online relationship. The computers in communicating allows for the science bit, along with the cold hard facts of distance. The latter is causing them to grow apart. And romance? It's what she craves. This is definitely a theme song of mine. Although my explanation probably didn't make much sense...
