"Yours" by Jin is the main theme OST for a Korean drama "Jirisan" released a month ago. Right after the release, it has set the record of being the fastest Korean solo song to achieve 80 and 90 #1's on iTunes in history (7,5 hours and 31 hours). It has also achieved the highest number of #1's for a solo song in 24 hours - 86. The song reached #1 on iTunes in the USA in mere hours (surpassing the new releases of the biggest western artists) and in just 2 hours in Japan, being the fastest Korean song to do so. It is also the first Korean solo song to stay #1 on Worldwide iTunes for 3 days since PSY in 2012.
Not so long ago, "Yours" surpassed "Easy on me" by Adele and became the solo song with the most #1's in 2021 with 99.
On December 19 "Yours" became the fastest Korean solo song to reach 100 #1's in the history of iTunes in just 1 month and 12 days.
"Yours" by Jin truly became a Korean OST that paved the way for OSTs by Asian artists into the Billboard and global charts. It set dozens of records in just a week after release. Currently, it is the most successful OST ever released by a Korean artist. Overall, Jin now has 2 solo songs with over 100 #1's on iTunes.
