Post the beep song controversy, STR and Anirudh have maintained a distance and resisted from working with each other. And, they seem to be back on track. STR has crooned a special number 'Peiyophobilia' under Anirudh's music for the upcoming horror thriller Rum.

Produced by Vijaya Raghavendra of All in Pictures and directed by debutante Sai Bharath, the film has Hrishikesh, Sanchita Shetty, Miya George, Vivek, Narain, Amzath, and Arjun in the lead roles. “While I was composing the ‘Peiyophobilia’ track, I felt Simbu's would be the perfect one for this number. ‘Peiyophobilia’ asks whether we should fear for ghost or not, further, the song will unveil the truth that the existing world is scarier than ghosts. We are pretty sure that ‘Peiyophobilia’ will be completely out of the box,” Anirudh said in a press note.
