Oddly enough, I almost wrote them off back in 2012 when I heard "These Days" on the radio, and I was like, "Hmmm, maybe this band may not be for me if this is their latest offering."
Suddenly, when I heard "Walk" on the radio, and just really loved the upbeat energy to it. Then, I saw the music video, and heard that the WWE used it for a tribute video for retired superstar, Edge, at his request, for their Hall of Fame which sealed the deal for me.
Then I watched their proshot set in Wembley Stadium and that made them a fave five band to me.
