Shawn Mendes Replaces Himself at No. 1 on Billboard + Twitter Top Tracks Chart

As "Mercy" succeeds "Ruin," the singer-songwriter is now one of three acts to unseat itself from the top.

Shawn Mendes’ “Mercy” flies 10-1 on the Billboard + Twitter Top Tracks chart (dated Jan. 14), knocking his own “Ruin” from the top slot. With the bump, the singer-songwriter becomes the third act to succeed itself at No. 1. The previous two? Justin Bieber, whose “Sorry” replaced “Love Yourself” on the Jan. 30, 2016, ranking, and Zayn, who achieved the feat twice consecutively when “It’s You” topped the list dated March 19, 2016, and was succeeded by the No. 1 reigns of “Like I Would” (March 26) and “Befour” (April 2).

Billboard + Twitter Top Tracks is a weekly ranking of the most shared and/or mentioned songs on Twitter in the U.S., ranked by the volume of shares over a seven-day period (Monday to Sunday). The newest chart’s tracking week ended on Jan. 1.

“Mercy” moves after Mendes’ tweeted that the song hit No. 1 in the U.S. iTunes Store chart on Dec. 26. The placement foreshadowed a big sales total for “Mercy,” which sold 119,000 digital downloads in the week ending Dec. 29, according to Nielsen Music, ranking at No. 2 on the Digital Song Sales chart and spurring a 28-17 ascent on the Billboard Hot 100. It’s the fourth top 20-charting single for Mendes on the Hot 100.

Just below “Mercy” on the Billboard + Twitter Top Tracks chart, Wyclef Jean and Young Thug’s “I Swear” re-enters at No. 2, besting its previous high of No. 14 and giving Jean his first top 10 on the chart since it launched in May 2014. Jean promoted the Dec. 8-released music video for the track during the tracking week ending Jan. 1, triggering the song’s arrival. The clip has surged to 431,000 global views on YouTube through Jan. 4.

“Swear” also secures Young Thug’s third top 10 on the list and claims his best showing among 15 chart entries to date. The song surpasses his previous high, a No. 4 peak for “Pick Up the Phone,” with Travis Scott and featuring Quavo, last October.

Meanwhile, Musical.ly breakout star Jacob Sartorius claims his first Top Tracks hit as “Last Text” enters at No. 9. The tune -- which is the title track of the singer’s debut EP, due Jan. 20 -- arrives thanks to chatter generated by its lyric video, which premiered Dec. 22 and has blazed to 4.3 million global views on YouTube.

Sartorius, who already has two Hot 100 credits to his resume -- “Hit or Miss” (No. 72 peak) and “Sweatshirt” (No. 90) -- has benefited from a wave of social buzz, which crested to new highs in 2016: According to Google, he was the ninth most-searched artist of 2016, ranking directly behind Kanye West and just ahead of Guns N’ Roses.
