Life Sim is to date the only artist on the PC Music roster to remain anonymous. Fans and critics have variously speculated that Life Sim is anyone from A. G. Cook to Spinee to Finn Diesel, with no conclusive results.

Life Sim has released two solo mixes, All Life and This Life, as well as a collaborative mix with A. G. Cook. They have also remixed a few tracks, PC Music and otherwise, and a few solo singles.
