What does it take to be deemed the "song of summer"? Well, it needs to be a song that as soon as you hear it, you'll suddenly start singing and dancing along to it.

We narrowed down a list of 32 contenders to compete for the title of Enstars Readers' Choice Song of Summer 2015. We have a mixture of genres here!

There will be polls for each round of the tournament, running for a week each. At the end of each round we'll post the results and then continue with the next round of polls.
