Not aware if anyone had sung Sultan song before

Singer Rahat Fateh Ali Khan says he was not "aware" that the song which he sang for Salman Khan's ‘Sultan’ was originally recorded by Arijit Singh. Recently, Arijit had written a public apology to the ‘Bajrangi Bhaijaan’ star asking him to retain a song which he had sung for his upcoming film directed by Ali Abbas Zafar.

According to the reports, the song "Jag Ghoomeya" was initially recorded by the "Tum Hi Ho" singer, but was, however, re-recorded in Rahat's voice.
When asked about this, the singer told reporters, "First of all, I was not aware if anyone had sung it before. I just came, I sang the song and that's it.

What happened after that I don't know." The singer was speaking at the launch of T-Series' new single ‘Dillagi’. The song has been composed by Salim-Sulaiman and features Vidyut Jammwal and Huma Qureshi.
