This week’s #MusicMonday song is Billkin – ‘Knock Knock (รักแรกพบ)’. 

Born in Bangkok, Thailand, Putthipong Assaratanakul is better known by his stage name, Billkin. His stage name, Billkin, was adopted after his brother called him “Billkin” instead of the nickname his father had given him, “Bill.” Billkin is well-known for his acting skills in addition to his singing career. He appears in the films How to Make Millions Before Grandma Dies, My Ambulance, and I Told Sunset About You.

Putthipong Assaratanakul was born in Bangkok, Thailand on October 8th, 1999

The movie The Red Envelope (ซองแดงแต่งผี) was released in Thailand on March 20, 2025. ‘Knock Knock (รักแรกพบ)’, one of the movie’s lead tracks, was released by Billkin. The song’s catchy lyrics make it lively and entertaining. The use of repetition and play on words adds to the silliness and light-heartedness of the song. 

I want to knock, knock, knock, knock, the door of the heart room.

Can you open it? If you don’t want to, I’ll break it.

Can you hear my heart? Let the sound of love reach you.

You can listen to Knock Knock (รักแรกพบ) on all streaming platforms!
