So far, Garrix has released three of the promised seven songs, each being previously unreleased IDs he's been dropping in sets for some time. The first, “WIEE,” is a light-hearted and giddy collaboration with Mesto. “Sun is Never Going Down” with Dawn Golden plays on festival-anthem drums and vocals. The latest, titled “Spotless,” features Jay Hardway and some really cool, playful melodic runs. It's the biggest, fattest of the bunch so far. What comes next?
