Grand Theft Auto IV, released in 2008, put a working mobile phone at the centre of its story, so its ringtones and alerts quickly became part of the game's identity for players. Short clips from that phone were later shared online as downloadable ringtones, and the Tonight melody has stayed popular with fans who want a recognisable GTA sound without using a full song. It sits alongside other series sounds, from the GTA V notification to the classic line associated with CJ from GTA SA, as a compact piece of open-world nostalgia.
