"Tough Love" comes in the form of duet with Swedish artists Agnes and duo Vargas and Lagola (who have a long and trusting work relationship with Avicii). Stating that he wanted this song to specifically be a duet between a real life couple, Avicii's wishes were fulfilled in the form of the vocals of Wife and Husband Agnes and Vargas (real name Vincent Pontare). Providing the soul of the track with beautifully sung lyrics that glide over the signature sounds of Avicii expertly, the two singers are the perfect match for Avicii's vision of "Tough Love". The violin sounds add even more heart and soul to the track, creating something unique but yet still typical of Avicii, which is nothing short of magic. The Indian influences heard throughout are reflective of what Tim was exploring at the time of creating the track, inspired by his extensive travels since retiring from touring.
