Never mind that Ultra already has four anthems sorted out already, Avicii's "ID2," a track that's been lingering unreleased for the past few years, is set to be released March 19 as a 2013 UMF anthem. And it makes sense. "ID2" is a track that just screams "festival anthem," an Avicii is known for holding onto tunes for a while. Regardless, this track will do damage during the six-day 2013 Ultra Music Festival, guaranteed.
