Rules on ceremony music?

I'm an alt bride and music is really important to me, so I'm struggling a bit to curate a list of songs to present to our registrar for suitability checks. Can anyone advise on how strict they are with profanity, like where is the line? To me some of the songs don't have profanity but it might be subjective? E.g some of the lines are "lord have mercy" (Shut up and Kiss Me - Whitesnake), "you could drag me through hell if it meant I could hold your hand" (Follow You - Bring Me The Horizon) etc. If there are any other alt brides here with experience of this I'd love to hear your stories!! Thank you
