Are songs sung by Salman Khan heavily autotuned?

For someone who once said that-" He can't sing to save his life", Salman Khan surely has sung and recorded a lot of songs but there are serious doubts about his songs being autotuned or being sung by an entirely different singer.

As much as I love Salman, I am no fool. His songs were definitely autotuned because he himself once said in an interview-"If the sur is okay then the technicians take care of it". He is an amazing actor and I love his work but he is not the best singer around.

Here is a list of his songs that I liked no matter how autotuned they were-

1. Main Hoon Hero Tera

2. Hangover

3. Jag Ghumeya

4. Pyaar Karona
