I've been playing this song nonstop lately. It is just so catchy and easy to sing along to. It also really reminds me of a past relationship and definitely would have been a past breakup anthem.
The video is rather strange though. Also, Glee did a really good version of it with Blaine and his brother, Cooper (guest Matt Bomer). I'll leave you with both versions to rock out to!
