Buble was very unlikely to have been heard on the radio at that time. I was hoping to write that he hadn’t been born, but he was in fact already alive - he’s significantly older than I knew about - https://en.m.wikipedia.org/wiki/Michael_Bubl%C3%A9
Nevertheless, he wasn’t very old, and was only just starting to push forward as a young talent.
CDs had been invented, but few (if any) cars had CD players. Most were still equipped for tape cassettes, as well as FM/AM radios.
