Baby, this is what you came for — a summer anthem that is 100 percent unquestionably THE song of the summer. Thanks to DJ Earworm, it's finally here. The YouTuber, known for his impressive year-end mash-ups, combined 19 of today's biggest hits into one catchy four-minute tune that you'll be playing on repeat for the next three months.
