Marshmello released Alone in 2016 as a standalone electronic single, and it quickly became one of the producer's signature tracks thanks to its catchy, upbeat drop. The masked DJ built a huge online following through gaming culture and YouTube, where the track was widely used in montages, intros and fan edits. Its simple, energetic melody made it easy to recognise even in short clips, helping it travel beyond dance music fans. Years later, creators still reach for it when they want an instant, familiar burst of excitement.
