Feby Putri occupies every central creative space for Senyum Semu, the Indonesian pop track whose official lyric video frames this official release. As the track’s primary creator, she penned all lyrics, composed its core notation, contributed backing vocals, and co-produced the full work alongside lead producer Adam Febrian, who also adds his own backing vocal performance to the track. The full recording process unfolds across two dedicated studio spaces, with mix engineer Reki Risanto shaping the track’s final layered sound at RR Studio, before mastering engineer Dimas Pradipta put the finishing touches on the recording at Sum It! Studio, locking in the track’s polish ahead of its inclusion on the full Hitam Putih album, where it appears as the fifth track on the project’s official tracklist.
