He bought the beat of an online store for a mere $30 in October last year.

And Lil Nas X's return has been immersible, with the singer's Old Town Road becoming Billboard's longest ever running number one single after remaining in the top spot for an impressive 17 weeks.

The 20-year-old's song featuring Billy Ray Cyrus, sees him knock off 2017's Despacito (by Daddy Yankee, Luis Fonsi and ) and 1995's One Sweet Day (Boys ll Men and ) - which were tied at 16 weeks.

Lil Nas X, real name, Montero Lamar Hill, took to social media to share his gratitude and excitement over the record.

'Last year in october [sic], as a struggling artist [sic] starting to lose faith in what i could be, i went looking for beats on youtube [sic],' he began.

'i remember clicking on so many generic sounding beats [sic] trying to find the right one for me [sic]. when suddenly i came across a country-trap [sic] sounding masterpiece [sic].'

'i immediately knew i would make something special out of it [sic]! my sister told me i had little time left before i had to leave her house [sic] after being there for months [sic] promoting my music [sic]online [sic] and not helping [sic] her out much,' he confessed.

Lil Nas X continued to explain that he used his sadness as motivation to create the best song he possibly could.

i was so upset [sic]! i used it as motivation for the song [sic]! i jokingly/seriously saw myself as a loner [sic] cowboy[sic] needing to [sic] run away from it all [sic]! I went out [sic] on my sister’s back porch [sic] and listened to the beat [sic] OVER [sic]& OVER [sic] & OVER[sic]!!'

He continued: then it came to me[sic]!! in my best singing voice [sic] i sung [sic] “YEAHHH IM GONNA TAKE MY HORSE [sic] TO THE OLD TOWN ROAD [sic] IM GONNA RIDEEEE TIL I CANT NO MORE [sic]” I LOVED IT ALREADY!'
