I was all prepared to post a specific song today, but when I went into YouTube to grab the link to the video, I just found this song today as a suggestion. It is another song by RADWIMPS (sorry for focusing on them!), Light the Light. I would ask that you also take a moment and go to YouTube and read the post the Band included with the video. This is why I picked this song today over the song I was going to use (which will be tomorrow's).
Enjoy!
