At long last, Adele is back -- and she’s back in a familiar spot: No. 1.

The British singer’s return dominated social-media discussion this week, and her comeback single “Hello” surged to No. 1 on the Billboard + Twitter Trending 140 chart, where it has taken residence in the chart’s penthouse across 17 consecutive hours.

“Hello” is Adele’s first charting single on the social-media-based survey, which launched in May 2014. The song is Adele’s first new single since “Skyfall," the theme to the James Bond film of the same name, which was released in late 2012.

Adele Reveals Release Date, Tracklist for '25' Album

The “Hello” rise to No. 1 caps off a busy week for the Grammy and Billboard Music Award-winning songstress, whose return to the music scene caught listeners by surprise. Adele began teasing her comeback on Oct. 18, with a short snippet of her latest single airing during that evening’s episode of the U.K.’s The X Factor. On Wednesday (Oct. 21), she posted a lengthy note to her Twitter and Facebook accounts, apologizing for the four-year delay between albums and revealing that her upcoming album’s title is 25. The following day, an Instagram post on her newly made account confirmed the project’s release date: Nov. 20.

25 marks Adele’s third studio album and follows 2011’s massively successful 21. Among its many accomplishments, the set logged 24 weeks leading the Billboard 200, the longest run at No. 1 by a female artist. 21 launched three No. 1 singles on the Billboard Hot 100, “Rolling in the Deep,” “Someone Like You” and “Set Fire to the Rain.” The success of 21 also scored Adele six Grammy Awards, including album of the year, and 13 Billboard Music Awards.

21 has sold 11.2 million copies in the U.S., according to Nielsen Music, making it the 10th-biggest selling album since Nielsen began tracking sales in 1991.
