Is this is sincere question? Or just thinly veiled marketing that you have a feature that a radio doesn't? Because you have to admit that a simple radio is absolutely your competition. If you have features that people should know about that make your solution the better one, just state them.

Marketing works when it is simple, concise, and honest: "I have product X that resolves problem Y, with features Z, and want people to be aware of it."

One of my past workplaces had the same audio/music that they got in the reception area.. non-stop soft/elevator music.

It was the same speakers that were used for announcements/fire-alarms/evacuations/etc. so the infrastructure was there to begin with.

I don't know what are the rules for "playing music in the office" (licensing etc. - it's not a resto, and it's only in the bathroom), but I remember 20+ years ago when I was a sys-admin tasked to find 'music for our call-center' I found some nice royalty-free music.
