In order to capture the essence of London in the late 1960s, and give the feeling of the British crime scene from the period, Rockstar decided to license music from the era. This would be the first use of licensed songs in the game series, a feature that would become recurrent in subsequent games. In addition to these licensed tracks, Rockstar again created some original songs, these also fit in the era depicted.
It is worth noting that the subsequent expansion, Grand Theft Auto: London 1961 uses this same soundtrack even though all the songs were released after 1961
