Who can develop an incredible app for my music company?

A prominent Canadian music label's marketing department is my responsibility. We have been working in this industry for nearly eight years. We recently made the decision to move to the United States state of Florida. Due to the importance of mobile apps in this industry, I was advised to hire an top enterprise mobile app development company to have our company's app designed by experienced developers. I would greatly appreciate it if you could recommend any additional high-quality, reputable app development company.
