I’ve not been able to run recently and I’ve been practicing the keyboard instead. I hadn’t heard of Despacito until an hour ago, when it had 8 billion views on Youtube.

And, I say this modestly, I got the three star maximum for my playing, though the app also tells me I was in time for just 75 per cent of the song
