“I’m Addicted” is an electro house song with a synthy breakdown and a 90s house chorus. The song talks about being addicted to love, comparing the rush of hormones with narcotics. At the song’s finale the singer chants the album title repeatedly, a play on words of her name and MDMA, which, is the drug also known as ecstasy.

The song received positive reviews from music critics, who agreed that it will sound fantastic loud and hard on the dance floor and called it a catchy club tune. Critics also praised the lyrics and deemed as the best song on the album. The song charted at 124 on the South Korean International Singles Chart due to strong downloads prior to its proposed released. It was included on the setlist of The MDNA Tour.
