My dad is picking the song for our father-daughter wedding dance and he called me the other day to let me know one that he liked. I believe it was the song that my cousin and uncle used at her wedding last year. Is it rude to use the same song as them? Will guest even remember the song? Should I ask my cousin how she would feel about it? It seems like the song means a lot to my dad but I don't want to take something away from my cousin's day.
