In the latest update for Grand Theft Auto Online a lot of content was added, new cars, hang outs, music, etc, but one thing they failed to mention is that the original music from the first releases are starting to expire and they've removed one song from the game quietly. Normally this is done on the 10th anniversary because Rockstar do not like to renew the music license but this has happened earlier than that. Expect more songs to expire over the next two years, on the plus side, constant influx of dance music due to their new record label.
