"Thinking Out Loud" took 19 weeks to arrive at the top of the U.K. singles chart.

Ed Sheeran received an exciting package in the mail today: The "Don't" singer was given his Guinness World Records certificate for "the longest climb to No. 1 on the U.K. singles chart." He posted a picture of the award on Instagram but kept his pride low-key with a caption of: "That ain't too shit is it."

It took Sheeran 19 weeks to reach No. 1 with his hit single "Thinking Out Loud," between July 5, 2014 and November 8, 2014. The record was previously held by Celine Dion, who's single "Think Twice" took 13 long weeks to make it to No. 1 on the same chart.

"Thinking Out Loud" also made history by spending an entire year in the U.K.'s top 40. On the Billboard Hot 100, the track came very close to No. 1, peaking at No. 2 for an incredible eight weeks. That marked the most weeks for a song to peak at the second position since 2004, when Mario Winans' "I Don't Wanna Know," featuring Enya and P. Diddy (as he was then billed), also spent eight frames at its highpoint.
