This remix was originally released sometime in early 2010, though today was the first time I've encountered it. And I was hooked within the first 10 seconds.
With Theophilus London, Ellie Goulding somehow becomes sexier. Not possible, you say? Okay, I'll admit that the original song "Starry Eyed" is super awesome in and of itself. And while it's definitely less in-your-face than this track, I can't help but preferring this one. Perhaps you'll share that sentiment.
