Songwriting

Lennon and McCartney credited almost every Beatles song to both names — even when only one of them had written it alone. As teenagers they had promised each other to credit all songs jointly, no matter who did what when.

Write the chorus first. If the hook doesn't land, the verses aren't worth it — most successful songs are built backward from a line that sticks.

“Which line have you never gotten out of your head — even if the song around it was mediocre?”
