Awesome app, but I suggest...
I think app would be more popular if you didnt have to pay $60 for a subscription. Rather, why not add a coin system and rewarded videos/downloads. People could download apps or watch video ads to earn coins and buy songs. You still earn $$$ (maybe even more than currently) and people dont have to pay. Thus, more people are likely to keep the app and use it frequently. Just a suggestion
