Euphoria (BTS song)

The music video was released as a theme for 起 Wonder, a part of the Love Yourself series. In a nine-minute depiction, the video continues the "Bangtan Universe" story line that is incorporated in many of BTS's music videos.[2] BTS had previously hinted at the song title by displaying the word Euphoria during their live stage at the 2017 Melon Music Awards.[3] Upon release, "Euphoria" trended worldwide and searches for the word increased 2883%.[4] The song was also featured as the soundtrack to HBO's season 1 finale of Euphoria (TV series).[5]

The song was promoted at the 2018 KBS Song Festival on December 29, 2018.[6]

The video incorporates scenes from previous BTS music videos that continue their in-universe story, showing each member as a character with different backgrounds and struggles. Scenes from previous videos include member V jumping into the ocean, Jungkook getting beaten by thugs, and other members trapped in fires and rooms. Member Jin recalls the memories of the seven of them together. Debussy's Clair de lune plays in the background before the actual start of the song.

The song plays scenes of the members playing around together outdoors, happy and carefree, with parallels of certain scenes to previous videos. In one of these parallels, the song ends as the seven members revisit the seaside where V had jumped. The Clair de lune plays once again as this time, in a sort of alternate universe-like twist, Jin takes V's place at the top of the pier, ready to jump instead of V. While V appears to notice that something is off, Jin peers down at his friends and records them with his video camera. Seeming content, he smiles before his video camera topples into the ocean, implying that Jin has jumped.

The music video was directed by Yong Seok Choi of Lumpens.[7] The assistant director was Lee Wonju of Lumpens. Other key personnel were Nam Hyunwoo of GDW who was the director of photography, Song Hyunsuk from Real Lighting who was the gaffer, Emma Sungeun Kim of GE Production who was the producer, and the art directors Park Jinsil and Kim Bona of MU:E.[8]

The song started as a sole work by Candace Nicole Sosa with the title "Killing Time". Sosa contacted DJ Swivel for writing advice. It turned out the DJ was very interested in the song.[9]

Musically, it has been described as a song with "future bass leanings" by Billboard.[10] In an interview DJ Swivel explained how "Euphoria" was made. A guitar combined with a piano leads the opening of the song, and then drums were added. There are four different sounds used for the drums in the beginning. For the B-section the aim was to make it sound open and bright. The featured instrument there is the synth string sound, with a sub base anchoring the section. In certain sections of the song vocal chops were placed in it to complement the lead vocal. After B-section the chorus becomes the most important part of the song with it being built around a main stab chord sound.[11] The key of the song is in D major and is 105 beats per minute.[12]

In an interview with Billboard, writer Melanie Fontana recalled that she wanted the chorus to explode with something more "chanty" but the crowd could sing along easily too. DJ Swivel stated the song "goes through a lot of different emotions" from beginning to end.[13]

The Grammys described the song as "an art-pop rabbit hole looking to the future" while Billboard stated it was a big statement piece and set the overall tone of Love Yourself: Answer as optimistic.[14]

In the United States the song sold 15,000 digital copies in the first week of release, coming in at number twelve for the best selling songs in the country.[15][16] In Canada the song was the nineteenth best seller upon release.[17] Worldwide, it came in at number two for best selling songs.[16]
