US rock band Imagine Dragons (梦龙) released this song on April 2, 2012. This powerful song raises debate on its meaning. Some people argue it is about the environment. Others believe it’s about pursuing (寻求) breakthroughs (突破). The leader of the band, Dan Reynolds, says: “It’s a song about awakening; kind of waking up one day and decide to do something new.” Regardless (不管怎样), it tells us how to see life in a fresh way.
