Sounds like an attorney with visions of winning the "lawsuit lottery". Complete nonsense. You actually CANNOT copyright the lyrics and music separate. No one STEALS anything, that is a myth. Everyone borrows and everything comes from something else. I am sure this Lawyer will help you copyright the phrase "I Love you" since no one has ever done that before.

Probably be a good idea to not take legal advice from someone who specializes in personal injury. I hope you haven't paid him anything, because that is what he/she is worth. Make sure you sue HIM for Legal malpractice. Maybe he'll end up with the same attorney that had the recent "Led Zepplin/Stairway to Heaven" lawsuit that got laughed out of court. He got suspended from practicing law, is being countersued for all damages and court costs, and is getting everything he so richly deserves for bringing such a huge slice of idiocy.

Birds of a feather...
