Last month, the 90-minute documentary Lewis Capaldi: How I’m Feeling Now premiered on Netflix. Its effect on the singer’s sales figures was almost instantaneous. Singles that were dropping out of the charts suddenly reversed their course. When his latest, Wish You the Best, came in at No 1, Capaldi had three singles in the Top 20. For good measure, he also had a Top 5 album, 2019’s deathless Divinely Uninspired to a Hellish Extent having also enjoyed its umpteenth surge in sales and streams.
