iPhone album artwork different to that on my iMac

iPhone 14 pro is showing different album artwork than the artwork showing in Music on my iMac.

This is happening on a handful of albums (not all). Artwork from completely different albums is being shown. For example, 'Air - Walkie Talkie' is showing the artwork form 'REM - Eponymous'. The REM album is okay and is showing it's own artwork.

This is a brand new iPhone 14 pro, upgraded from an iPhone x. The artwork on the iPhone x is all correct.

I've tried re-syncing the music library with the iMac and the problem persists.

How do I correct this?
