We looove it when two songs fit together like a hand in a glove. It makes us so happy inside! Now, unless you've been in hiding the last year or so you have heard the blockbuster hit Somebody That I Used To Know from Gotye featuring Kimbra. Yes? Good. Can we treat you to this really great mash-up with Ellie Goulding's Starsmith produced album track Your Biggest Mistake? We hope so! They sound awesome together! Perfect match. Click here for Ellie's original and here for Gotye in case you wanna compare!
