In late July, “Old Town Road” made history by becoming the longest-running No. 1 single to ever top the Billboard Hot 100 Chart.

Lil Nas X thanked his fans and followers in a lengthy Instagram post, recalling how he was a “struggling artist” less than a year ago and sharing how his life has drastically changed for the better.

“Did I know it would become the longest running number 1️⃣ song of all time? NO! but I am so thankful that this blessing has been placed upon me,” he shared. “This song has changed my life and the way I see the world around me in less than a year.”
