Here, 'the loneliest whale in the world'.
so-called '52 Whale' Singing at a high frequency of 52 Hz, the whale can't talk to other ordinary whales that communicate at frequencies of 12-25 Hz.
Nevertheless, the 52 whale continues to sing. Alone, steady.
Born in a combination of 52 Whale and 'Alien', the song is as lonely and hard as a 52 Whale, but it melts the feelings of bts, who has no choice but to continue singing.
In the early 2000s, the song was created with a high-pitched vocal sampling technique that allows users to feel the vibe of hip-hop, along with an old-school rhythm source, creating a lonely yet nostalgic feeling.
