Two songs

I was driving in Spain, and we had Spanish radio on. So far they had played just Spanish songs for the whole journey. One was quite a catchy tune, so I turned to my son and idly said “it’s a shame there aren’t more tunes like that, where you pick up the tune the first time you hear it. It’s a bit like that song last year from Kelly Clarkson, you knew as soon as you heard it that it had a good tune. What was it called now? The …. something… song. Ironic! Can’t remember the title!” As I was racking my brains, the Spanish song finished and the Spanish DJ rattled off a quick-fire Spanish link, none of which I understood apart from his final word (in a heavy accent): “…..Kelly Clarkson y The Heartbeat Song!” at which point the song started playing, even though it had last been in the charts over a year ago. What were the chances? Then the next day I was driving through the Spanish mountains with a different Spanish radio station and we saw lots of lovely purple flowered trees. I absent-mindedly started singing ‘purple trees, purple trees’ to the tune of Prince’s Purple Rain. Sure enough, 3 minutes later the radio started playing Purple Rain by Prince.
