Ok so i heard this being blasted out of the car and have been searching everywhere for the name of this song. I think it is from a Bollywood film. I could only remember one line from the song:

"Jaga (or jatha/chantha) main akela rajai re"


Thanks in advance to any answers.

Is this the song you were thinking of? Alka Yagnik & Udit Narayan - Sajan Tumse Pyar Ki Ladai Mein - Maine Pyaar Kyun Kiya (2005)
Here is a video - I hear the line you mentioned around 1 minute and 18 seconds.
