What is this Bollywood song? (listen and tell me please)?!

I heard this song on the radio the other day but the guy never said what movie it was from or what it was called!. I don't know of any good mp3 hosting sites so I did the best I could so you can hear it (I recorded it with my phone)!. I KNOW I should know this song! I'm just terrible I have NO CLUE what it is!

Please listen to the song and tell me if you know it!.
