#1. Getting past the rust.
Write literally the most cliched lyric you can think of.
Really squeeze that juice. Just write the most trashy, obvious, cliched thing you can muster. String together cliches. Write the cheesiest love song you can.
Aim for a Verse and Chorus.
Set to music if you have time.
