Loneliness

This track, included on the album ANTENNA released in July 2023, squarely asks how we confront loneliness.

It portrays the protagonist’s introspection as they try to take a step forward despite their weakness and sense of stagnation, with lyrics that are striking for the heartbeat that emerges not by rejecting loneliness, but by accepting it.

In live performances, it’s unveiled amid a spectacle of pillars of flame in the darkness, and despite being an album track, it instantly raises the venue’s energy with its commanding presence.

The sound—where dark emotionality coexists with the driving force of dance music—is truly one of a kind.

It’s a song that quietly stays by your side on nights when you want to face yourself or when you want to confirm the feelings deep in your heart.

It’s a track from the album “Chandelier,” released in December 2015.

It’s a song you’ll want to hear if you’re in a one-sided love or struggling because the person you like won’t look your way.
