"How Long" was first mentioned online in August 2007, when a user on a Ukrainian forum mentioned that a snippet was featured on the menu of a Russian
bootleg DVD. A small group of fans formed to uncover its origin. Only a low-quality, 45-second snippet of its chorus was available. The search became popular in the
lostwave community, which is dedicated to trying to identify the provenance of songs considered unknown or
lost. Because it was never released commercially, it was not possible to find it through
Google or apps like
Shazam. Fans initially named it "How Long Will It Take", based on a line from the chorus. Some people made tribute videos for "How Long" featuring images of
teddy bears, while others created remixes and covers of it. Additionally, video essays were made about the mystery. In October 2023, a
subreddit, r/HLWIT, was created, named after the initials of the unofficial title, and had one thousand members by December. On December 8, 2023, sixteen years after "How Long" was first mentioned on the Internet, Reddit user "the-arabara" posted that he had found its origin. Initially, he tried to find the creators of the DVDs, "track[ed] down a movie mentioned on a job application", and found another obscure song in its credits. Ultimately, he found "How Long" when searching for songs titled "How Long" on the
Society of Composer, Authors and Music Publishers of Canada's database. This led him to another Reddit post and ultimately to a podcast containing the full song. Reddit users commemorated the discovery on r/HLWIT. That same day, Toledo got multiple emails about the discovery, which surprised her; she initially believed the messages to be scams. In response, she released the full version of "How Long" on
Bandcamp on December 13. All proceeds from its sales in 2023 went to the Music Heals Charitable Foundation, which supports and raises awareness of music therapy. Later, Toledo released "How Long" on streaming services, including
Spotify and
Apple Music. However, as a result of an unofficial duplicate version of it appearing on streaming platforms, the official version was taken down, which she suspected to be because of streaming fraud. In May 2024, it was officially reuploaded to streaming services under the title "How Long (Will It Take)". == Personnel ==
