Skyline was one of Samsung's default notification sounds, widely heard on Galaxy phones during the 2010s as the alert for incoming text messages. Because Samsung phones were so common, the short chime became instantly recognisable even outside the phone itself, and it later spread through ringtones, soundboards and short video edits. Creators still use it today because it instantly signals a phone notification without explanation, while also carrying a clear mid-2010s nostalgia for viewers who remember that era of Android phones.
