In Da Club was released by 50 Cent in 2003 as the lead single from his debut album Get Rich or Die Tryin', and it quickly became a staple at parties and celebrations. Its birthday hook, built around the call to celebrate the listener's birthday, made it a natural choice for birthday playlists long before short video edits existed. As birthday clips spread online, creators kept returning to the same instantly recognisable moment because it signals celebration in seconds. That familiarity is why it still works for birthdays, surprises and party montages today.
