When pop and film collide and you see words like 'music from and inspired by' you can usually bet that the 'inspired by' part is a broad way of saying 'music retrieved from a leftovers folder, inspired by an email asking for any random old nonsense to chuck on a film'.

Not something you could say about the new Billie Eilish track When I Was Older, a song that's not from but def­in­itely is inspired by Sólo con Tu Pareja hitmaker Alfonso Cuarón's latest film Roma.

Upshot: a super-atmo­spheric moodtune that's probably one of Billie's Top 5 songs to date.
