Why He's Hot: DJ/producer Martin Garrix was unknown until this May, when the inexplicably catchy EDM instrumental "Animals" - which had been making the festival rounds as an unknown banger - was finally revealed to be his, right here on Billboard.com. The track was recently licensed to Casablanca/Republic by its original Dutch label Spinnin', and has spent 10 weeks on the Dance/Electronic Songs Chart, where it's currently No. 12. Its trouble-making video has nearly 24 million YouTube views to date. The blue-eyed 17-year-old was inspired to make electronic music after watching Tiësto perform at the 2004 Summer Olympics in Athens. When he was eight.
