Unfortunately, it's not possible to use Spotify in public places (such as bars, restaurants, stores, schools, etc.). You may only make personal, non-commercial, entertainment use of the content and, in signing up for an account, you have agreed and undertaken that you are using the content only in this manner.
Spotify Business is a commercial license subscription level. It enables you to legally stream and download music from Spotify and play it to anyone visiting your business. Start building the sound of your brand here.
