There are few songs that instantly give you the euphoric feeling every time you hear that song. “Levels” is one of the songs. Despite introducing an early instrumental during an appearance on BBC Radio 1's Essential Mix in December of 2010, Avicii didn't actually premiere “Levels” with Etta James' vocals until Ultra Music Festival in March of 2011.

Since its release, “Levels” went viral with millions of plays from around the world. Several critics even consider “Levels” being one of the best EDM songs of all time due to its euphoric melodies, and Avicii's incredible way to entice his listeners.
