A period at the end of a line
Apple Music lyric guidance explicitly excludes commas and periods at line endings. The current Genius guide separately requires question marks for questions and uses exclamation marks for excitement, but does not state the same blanket ban. Removal is preview-only so quotations, abbreviations, and intentional delivery remain reviewable.
Convention: Questions always end with a question mark.
Example
[Verse]
A lyric line.In the workbench this reads: Lyric lines should not end with a period.
[Verse]
A lyric line!The fix
In the workbench this finding carries one control, labelled Remove the period. The change is contextual, so it is previewed as a diff in your document first and applies only when you confirm it.
