This was actually very enjoyable! I don't often do crossword puzzles. You had such a creative take on it too, thanks for sharing it with the WdC community. It's perfect for the month of February! It also reminded me of so many beautiful songs that I love and haven't heard in a very long time. Now, I want to listen to some of them again. Now, look what you've gone and done.
To fulfill your request:
I solved it with the following word list, in order:
(Across) Kick, marriage, stupid, night, romance, coins, under, jealous, strangers, love, luck
(Down) Know, close, you, way, best, mine, people, funny, thing, crush, look, all
Final Thoughts / Side Notes:
Thank you for sharing this, and for the fun challenge, and for the wonderful offer you put out to us all for completing this. How super-generous and it is much appreciated, secret ninja-monkey! Write on!
