Discord is a free voice and text chat app launched in 2015 that became the default hangout for gaming communities, and its short message notification quickly became one of the most recognisable alert sounds online. The chime spread far beyond the app itself: meme editors drop it into videos to fake incoming messages, streamers use it as a donation or chat alert, and compilation channels build entire jokes around notification spam. Like the GTA V notification, it works because the sound is short, clean and instantly familiar to anyone who spends time online.
