Poor, slow and terrible app, but great music service

The app development is a nightmare for me. It takes ages to load in my relatively new iPhone 6s plus and it loads on my iPad after 5-6 minutes. I dont have this problem with any other app, even high graphic games and other heavy utility apps. The interface is super slow and you will get frustrated soon. But their music service is great. Youll have downloadable high-quality music, radio and music videos for free with a fair amount of ad. But the app itself is just terrible. Icant imagine anything slower than this.
