Hello friends this app make you fool not a star because when I downloaded this app firstly it need your Facebook account then email for knok you again and again 5-6 times in a day but leave it I will talk about this topic later first the big thing I want to tell you that is waistage of your data in a large amount automatically it plays videos which takes allot data I used thia app 3-4 times only and I loose my 400 mbs. now you think how expensive app is this. Now we come on emails so that makes you irritating again and again that they sing a song they maked a video bla bla bla waisting of time and data too.this is my suggestion for those who are going to sing with this app.thanks
