Ed Sheeran has had himself quite the week. His two newest tracks, "Shape of You" and "Castle on the Hill," explode with Nos. 1 and 2 debuts, respectively, on the Billboard + Twitter Top Tracks chart (dated Jan. 21), making him the first artist to launch two songs in the top two spots simultaneously.
Billboard + Twitter Top Tracks (which began in June 2014) 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 Jan. 8.
"Shape" and "Castle" make their lofty debuts after Sheeran had teased the tracks leading up to their dual premieres Jan. 6. The pop singer-songwriter first announced the songs on New Year's Day, when he posted a video of himself holding a sign reading, "New Music Coming Friday!!" on his social accounts. The first 30 seconds of "Shape" was also teased in a Snapchat filter the day before it arrived in full.
