Because of the music licensing issues, Rockstar Games will have to remove some songs from Grand Theft Auto IV and Episodes From Liberty City. Most likely, Vladivostok FM will be affected the most. Rockstar Games promises to replace removed tracks with other ones.
Due to music licensing restrictions, we are required to remove certain songs from the in-game soundtrack of Grand Theft Auto IV and its Episodes, in particular a large portion of the Russian pop station, Vladivostok FM. However we are replacing some of those songs with a new set of songs on that station. We will update our customer support website with new information as soon as it is available.
