File under: Best. Song. Ever. Well, today, anyway. Such is the conceit for our latest feature, the cleverly dubbed Song of the Day. Today's song, a bewitching number called "Big Jet Plane" by Australian siblings Angus & Julia Stone. Hometown hit maker Frank E turned us on via a tweet earlier today, and we haven't been able to stop listening since. The riff it's built on is rather simple, and the words are relatively sparse, but there's something about the tune that just flips our wig. And the video's pretty rad, too. Nothing like being left to your own devices in a party store. Have you heard a new song that's better than this one? Tell us about it. We're always on the hunt for new music. What are some other new songs should we fill our listening device with?
