Update: Rockstar has confirmed that music will be removed from the game, but it plans to make up for that by introducing new songs in their place. A spokesperson told GameSpot, "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." The original story follows.

As incredible as it is, Grand Theft Auto IV is coming up on its tenth birthday later this month. And this means that some music licenses will expire and Rockstar will have to remove a bunch of tracks from the game's soundtrack.
