Shreya Goshal voice in this song sound very odd

I love shreya but here Shreya sounded so odd in this song dont know what was the reason ...no wonder that anu malik had to solo this song with sonu nigam which is so beautiful... and the solo version was kept in the film ...legendary composition though ... keep coming back to this song years after years... the adventure, the thrill, the suspense created in it is superb! ~~~Pighlainge hum is chandni mein Kab tak ghulainge badan? Pyasa hae dil, pyasi ye rut hae Chubhne lagi har kiran~~~
