Anyone been watching “Grey’s Anatomy” this season? Then you know Scars on 45, a British indie-pop band whose song “Heart On Fire” is in heavy rotation on the season promos. The band (think: Snow Patrol and Keane) are releasing “Heart On Fire” as their 2nd EP with Chop Shop/Atlantic. It’s in the Top 15 at Triple A radio and number 40 at the Hot AC radio. In other words, you’ll want to watch this video yesterday. What are you waiting for?
