I had not used a jukebox in about 30 years. Of course, it was a touch screen and computerized. Thus, I had little idea on how to use it, to understand the "logic" under the black box. I did manage to inject The Who a few times between more Celtic cacaphony, but was not sure about the mechanism by which the music was played. Yes, you get three tunes for $1, but they do not play in a row.
One more example of decision making and control being given over to "the Cloud" (meaning: digital instrustion beyond our ken and always in our midst).
