www.karaokeparty.com is a web based version of the playstation game “SingStar”.
Karaokeparty lets you croon along to your favorite tracks. You don’t need a microphone but if you do use one then the site will automatically rate your performance provided that you have registered.
Your score will be visible to other users and you can attempt to secure a place on the leader board. You can also make friends and chat to other singers.
