Proof is the first anthology album released by South Korean group BTS, on June 10, 2022, through Big Hit Music.

It also includes five new songs: the album's lead single "Yet to Come (The Most Beautiful Moment)", "Run BTS", "For Youth", "Quotation Mark", and "애매한 사이" (Young Love).

On December 5, 2021, in conjunction with an announcement that BTS would be devoting more attention to solo projects, Big Hit Music revealed that preparations for the release of an upcoming group album were underway.

[5] Per a subsequent notice posted on Weverse and shared via Twitter, the three-disc album comprises tracks spanning the past nine years of the band's discography, as well as three new songs.

[10] Originally released for free by the band shortly after their debut, the song samples "Born Sinner" by American rapper J. Cole from his album of the same name.

[21] The streaming service announced via Twitter on May 31 that the group broke the record for the year's biggest show with the first episode of #BTSRadio on Apple Music 1.

[22] The band members' statements, unique content, and a countdown to the album release were all featured on Spotify's #SpotifyPurpleU immersive microsite experience.

From June 3, billboards with the hashtag #SpotifyPurpleU appeared worldwide, including in South Korea, the US, Brazil, Mexico, Japan, the Philippines, Indonesia, Thailand, and Vietnam.

At the end of the month-long challenge, a tribute video honoring a few of the shorts produced by the fans using the album title track will be made available on BTS' official YouTube channel.

An alternative hip-hop track co-written by RM, J-Hope, Suga, longtime producer Pdogg, and American artists Max and Dan Gleyzer, the song's lyrics simultaneously reflect on the band's past while looking towards the future.

A hip-hop/rock track, it features a "thrumming"[32] repetitive guitar riff, and low-key growls of J-Hope, Suga, and RM are heard during the pre-chorus.

The song highlights in particular Suga's complex rapping style while showcasing Jimin, V, Jungkook and Jin's expert vocal abilities, as the singers "deliver some of the most soaring falsettos".

[32] The other is track four, "Quotation Mark", by RM, J-Hope, and Jungkook, which has a retro beat similar in vigor to BTS' 2013 song "Like", from the 2 Cool 4 Skool single album.

[36] The album's final song, "For Youth", opens with an audio sample from the band's 2019 concert at Wembley Stadium in London, of 90,000 fans singing along to "Young Forever".

[33] The lyrics frequently allude to "Spring Day", "Epilogue: Young Forever", "Friends", and various trials the band faced during the previous nine years.

[41] Natalie Morin of Rolling Stone praised the album, describing its lead single as "a classic BTS blend of sparkling pop and old-school hip-hop that offers a hopeful promise of an even brighter future.

"[43] For Times, Elizabeth De Luna cited that Proof shows "an evolution from early raw material to a polished global presentation.

"[44] In her review for Consequence, Mary Siroky explained how the band "unpack an unparalleled creative journey" through the 48 songs from different eras of their career.

[48] The album debuted at number one in South Korea,[49] Australia,[50] Austria,[51] Belgium,[52][53] Canada,[54] Finland,[55] Germany,[56] Japan,[57] the Netherlands,[58] New Zealand,[59] Poland,[60] Portugal,[61] and Switzerland.

[67] Proof sold 514,000 copies in Japan during the period dated June 13–19, recording the highest first-week sales on the weekly Oricon Albums Chart in 2022 and achieving the fifth-highest first-week sales of all-time in Oricon chart history, after Mariah Carey's #1's (1998), Boa's Valenti (2003), and BTS' own BTS, the Best (2021) and Map of the Soul: 7 – The Journey (2020).

Additionally, four of its tracks—"Born Singer", "For Youth", "Run BTS", and "Yet to Come"—were nominated in the Global Digital Music – June category,[84] with "Yet to Come" winning.
