This is the official song by Metric. It’s an incredible piece of music. Compare it to the one that was featured in Scott Pilgrim Vs The World. That one was sung by the actress Brie Larson, best known for her role in United States of Tara.
Between the two, I prefer Metric’s. The reason is simple: Emily Haines has got a better voice than Brie Larson. Still, Brie did a great job.
