Original artist: Robyn
Attempting a stripped-down version of Robyn is risky enough let alone covering a song that relies on her liveliness. However, Katie Stelmanis' operatic version offers a bleaker side to Robyn's lyrics, making the cover seem almost more appropriate than the poppy original. Don't be surprised if you can't listen to Robyn the same anymore.
