From 4-84, Never Stop Singing

Karaoke in the palm of you hand and so much more. Vocal filters as well as video filters help you edit your songs and videos. There is messaging now so you can get to know over 5million other singers. Duets and group sing. Pretty much any song you want is on here, plus you can just freestyle and upload your original pieces. The only bad part, it uses waaaaaay too much data. So hopefully you have wifi!
