I invariably listen to music whilst at work. To-day, a colleague did me a "favour" by tuning-in a music channel on the smart TV. He introduced it as: "Listen to this, it's great!"

It was non-stop rock & pop "classics", frequently interrupted by adverts. As if this wasn't bad enough, the songs weren't by the original artists. The songs were covered by people who were so no-names that they weren't even credited.

Out of politeness I felt obligated to listen to it for a while.

It was purgatory.
