Fre musics available here for jio users .i used it for some time but now I uninstalled it because its a bit slower than other online music apps and it takes some time to update new songs .but the quality of music is good and cost very low data and also you can download songs for free while the other music apps just give 1month for free and then yiu have to pay for it.so in that way it is a quite useful app for jio users.but I dont really prefer it .and I also use wynk music for online music.but if you like to downlaod songs than it is a perfect app for you
