Background music is a very tough business. This article was focused on the custom and boutique programming end for highly brand conscience clients. I co-founded Trusonic and competed with Muzak and DMX for several years eventually servicing 50,000 locations. It is a competitive business at scale. There are companies that are willing to pay top dollar for music programmers who will completely customize playlists for a brand, but these are somewhat rare and not necessarily the business one looks to engage due to the labor required.

I have the same question, but I'm now wondering if it's just a pun - as in 'booming' music etc.
