"No Mercy" appeared on the collaborative Prince Ital Joe and Marky Mark album The Remix Album, although this particular track is actually a solo effort by Marky Mark with no participation from Prince Ital Joe.

Wahlberg had struck a friendship with Polish boxer Dariusz Michalczewski.

Marky Mark released the track "No Mercy" a biographical song about Michalczewski, including excerpts in Polish from Michalczewski himself.

The boxer also appears in the music video[1] that was directed by Frank Papenbroock and Joachim Kirschstein.

The music video chronicled the early years of Michalczewski's life played by a young actor.
