Sing! Karaoke by Smule is an interesting application for Android that has a great idea behind it and lets you sing songs online either on your own or in group with other people from all around the world.

The application features an intuitive and simple interface that is divided into five sections: home where your performance history is stored, music where you can listen to how others sing, newsfeed, and your profile. Just tap on the middle button in the app menu, choose any song to your liking, and start singing.

Mind though that the app features very aggressive in-app purchases and at first you won’t be able to sing on your own, but will need to sing together with someone in a duet or group to get more points. Also, you will be able to earn points by watching promo videos.
