Jio Music is such an amazing app. That we can get any song at anywhr at any place in just one click. Click kro aur music suno. Love this app. I had recommended it to many of my friends And even they also enjoyed this app. It is not neccessary that you should have jio sim. then only you can instal it. Any one can instal it in any phone. 4G is not neccessary. You just need an internet connection doest matter if it is 2G or 3G You just have to download the app. from play store and after downloading you have to log in with any of your account i.e Gmail facebook . and its ready to use. it is very easy simply you have to type the song name and even you can download the song from JIO MUSIC app for free. Just download it once and am damn sure you will definitely like this app. As I had experienced it
