Patently Apple:

There’s a common misunderstanding among business owners that songwriters are only compensated by the purchase of their CDs, so that a business owner can freely play copyrighted music for customers. Not so, and Apple’s new trademark filing for ‘Apple Music for Business’ indicates that Apple will be entering this new business avenue for Apple music in the future as the company seeks to expand their services businesses.

An Apple Music for Business subscription, assuming it turns out to be reasonably priced, would be good for small businesses, give them an easy way to play music for their customers that is properly copyrighted.

And, presumably, it would be good for artists, who would be compensated by the service, getting something, rather than the nothing they get when a business plays a playlist.
