Imagine dragons is a popular band who has written many popular songs. All of the people in the band are guys. One of their most popular songs that plays on the radio is its time and radioactive. They also wrote other songs like bleeding out, tiptoe, on top of the world, etc. I personally love imagine dragons! they are great you should listen to them sometime!

Your best bet is to buy it from iTunes or your local CD store, places such as Amazon are also viable choices.
I like Imagine Dragons a lot, and some other bands that are somewhat similar are X Ambassadors and Mumford & Sons.
