Fun fact: House of Pain was white and Irish, too. Rep your heritage, rappers. Yes, Macklemore and Ryan Lewis' "Irish Celebration" is a song—with vintage videos!—all about Macklemore's Irish heritage and immigration. "Put a pint up/Everybody sing the song" is one of the lyrics. But, the real Irish OG rappers are House of Pain, and besides their insanely popular hit "Jump Around" they, too, repped their heritage with tracks like "Irish Pride" and "Top O' The Morning To Ya."
