Grand Theft Auto IV was released by Rockstar Games in 2008 and follows Niko Bellic in a darker, more grounded version of Liberty City. Its loading screen music became inseparable from the game's somber tone and from long waits before free roam. Fans later shared loading audio and unused files hidden in the game online, turning waiting music into a nostalgia staple. It is often grouped with the GTA V notification and the Aw Shit Here Go Again CJ line from San Andreas in fan edit packs and sound collections.
