Tunes Tuesday: "Obsessions," Marina & The Diamonds

I first heard this song on a mix from my friend, the fabulous DJ Lani Love. Take a listen to the original version here. It's an operatic but peppy take on all the little nagging thoughts that bug poor Marina every day of every week. If I told you that the chorus is "We've got obsessions/ You never told me what it was that made you strong and what it was that makes you weak," would you still believe me when I say that this is a lark of a song?
