Q: i need karaoke songs how do you contact anyone here

You can only Purchase items from iTunes that are available in the iTunes Store of your Country.

If the items you want are Not Available... you will need to look elsewhere.

You can request that content be added to the store via this page : http://www.apple.com/feedback/itunes.html

But ultimately it's the content providers (e.g. the record companies) that will have to grant Apple a license to sell their content in a particular country.  If the tracks that you want aren't currently available from iTunes then are they available on other music purchase download sites that you have access to ?
