Q: i clicked GIft Songs.. next it took me to... password... click billing info... i put in the credit card number .... and my card gets charged Rs 60 for a Rs 15 song... how is this... Second, I do not see the purchase, not it asked me whom to gift the song.

Have you added or changed your credit card details on your iTunes account ? If you have then each time that you do so a small temporary store holding charge may be applied to check that the card details are correct and valid and that it's registered to exactly the same name and address as on your iTunes account - it should disappear off your account within a few days or so.

Were you also charged for the song ? If not then do you get any error messages when trying to gift it ?

You should get a screen similar to that shown on the page that you posted from, allowing you to type in the email address of the recipient

My previous post was referring to the screenshots that show on this page : http://support.apple.com/kb/HT2736 - after selecting the 'gift' link (and possibly entering credit card details if the card isn't already on your account) you should then get a screen where you can fill in the recipient's email address. It is a credit card that you are trying to use ? I don't think that debit cards are still accepted as a valid payment method.
