This app constantly freezes or doesn't respond, it will sometimes take 2 or 3 minutes to respond and actually start playing music. I've had this experience on multiple phones of my own. And since I pay for the unlimited plan, I've gotten complaints from family members of the same experience on both Android (Samsung and Motorola) and Apple platforms. It used to work flawlessly, but over the past several years, it has continued to become more and more unreliable.
