First act to debut in UK Top 10 with two singles simultaneously

On the UK's Official Singles Chart dated 19 January 2017, British singer-songwriter Ed Sheeran debuted at No.1 with "Shape of You" and No.2 with "Castle on the Hill" – the first singles released from his third studio album ÷ ("Divide"). In the 64-year history of the Hot 100, no act had ever scored debuts at No.1 and No.2 in the same week. "Shape of You" was Sheeran's third UK chart-topper, after the 2014 hits "Sing" and "Thinking Out Loud".

"Shape of You" and "Castle on the Hill" registered 227,000 and 194,000 combined units (downloads and streams) respectively. Both songs smashed the UK's one-week streaming record – 8.9 million for Drake's (Canada) 2016 hit "One Dance". "Shape" and "Castle" racked up streams of 13.4 million and 11.07 million, respectively, for the week ending 19 January 2017. One Direction's (UK/Ireland) 24-hour record – 4.76 million streams for "Drag Me Down" – was also lost to the irrepressible Sheeran as "Shape of You" attracted 6.13 million streams on 6 January and 7.24 million streams on 9 January 2017.

On the Billboard Hot 100 dated 28 January 2017, Sheeran debuted at No.1 with "Shape of You" and No.6 with "Castle on the Hill". In the 58-year history of the Hot 100, no act had ever scored two Top 10 debuts in the same week. "Shape of You" was Sheeran's first US chart-topper.

In Australia, the two songs matched their chart start in the UK, which was a first for any act on the ARIA Singles Chart. "Shape of You" and "Castle on the Hill" also debuted at No.1 and No.2 across Europe and in territories such as Canada and New Zealand, breaking chart numerous records for simultaneous Top 10 new entries.
