There's nothing like a good answer song, and Wales' Marina and the Diamonds crafted a great one by opening up Justin Bieber's "Boyfriend" and rearranging its insides. If you were waiting for the female perspective on eating fondue, you'll be disappointed, but this does a really job of making the original's melody even ear-wormier while trimming the fat (i.e. the rapping). With a new Saint Etienne song called "Answer Song" having just been released yesterday, it's a good time for the medium. Check this space for my response to "Beez in the Trap," "Aunts on My Log."
