Unlikely...
yes, it’s possible...technically speaking, assuming the area affected was in the line of fire for the interference unleashed by the Solar event or the feed was. (I don’t have the map handy)
Muzak, (unless they have radically changed) is broadcast on a FM sub channel from a radio station. If you were on the outer area of the antennae range, the broadcast could well have been temporarily blocked, or the feed for the broadcast may well have been disrupted to the radio station as much of that comes via satellite or in some cases...a phone line.
Not knowing the particulars or location of the feed or the broadcast, I can’t say for sure what the potential for disruption was, but I have seen this happen before......and Muzak or it’s competitors use a variety of means to get the signal to the end user.
Having said all of that, the media does exaggerate these events quite frequently these days..The Ham radio guys may have a better handle on the issue.
