This game is good but it's really dumb. Lile I have great service and great wifi, but when I try and watch an ad to unlock a new song it won't let me. It says "your offline turn off your internet and try again later" which I have great service but I do it anyways. I also close and reopen the app after doing so bc it might be glitched but it's not. So if it wasn't for this playstore I would've gave the app 0 stars but since I can only put one star your lucky.
