Write texting shorthand out in full
Texting shorthand is a way of writing rather than a way of singing: the letters stand in for words the vocal performs in full, and Genius wants the sung words in standardized spelling. Initialisms that are themselves said aloud — ASAP, OK, VIP — are left alone. Check the delivery before replacing this, since an artist who spells the letters out is transcribed as they sing them.
Example
[Verse]
Idk what to tell youIn the workbench this reads: Use “I don't know” instead of “Idk”.
[Verse]
I don't know what to tell youThe fix
In the workbench this finding carries one control, labelled Replace with I don't know. The change is contextual, so it is previewed as a diff in your document first and applies only when you confirm it.
