Wiz Khalifa collabs with Vietnamese YouTuber on mixtape

Ytiet, real name So Y Tiet, claims to be a buffalo herdsman from central Binh Dinh Province. The 32-year-old YouTuber currently has over 330,000 subscribers.

He released a track on August 2 called "From 41 to 49," a counting song sung by Ytiet in English and produced by Retro Messiah, on his official YouTube channel.

Ytiet's initial video has raked in over two million views while the Number Song (From 41 to 49) video currently has nearly 600,000 views on YouTube.

Number Song (From 41 to 49), released on September 8, is the third track from a musical project called Big Pimpin’ consisting of 17 mixtapes compiled by Grammy-nominated Wiz Khalifa, best known around the world for his hit song "See You Again" featuring singer Charlie Puth that appeared in blockbuster "Fast & Furious 7". Other songs include "Black and Yellow", "Work Hard Play Hard", "Remember You", and "We Dern Boyz".

Last Thursday, Tiet shared on his Facebook page a clip of Justin Bieber vibing to the mixtape, which the Canadian singer previously posted among his Instagram stories, with the caption reading "My idol #justinbieber listens to my song. I am very happy."

The soundtrack quickly turned heads across different social media platforms, even becoming a dance cover on TikTok and Instagram.

Ytiet recently became a internet phenomenon after American rapper Snoop Dogg and singer Chris Brown reposted Tiet's TikTok singing clips on their official Instagram accounts.

However, the track received mixed reviews from the public.

Some viewers commented the lyrics were meaningless, counting only from 41 to 49, with some unsure why it became so popular. Fans hold the song blew up because Tiet has a unique voice and the song has a catchy melody and words easy to remember.
