I think we can all agree that This Day Aria is an epic and amazing song. It was a perfect piece for the drama of the season two finale. So it's no surprise that fans still love this song and want to create resources for it.
A fan named MissDarkAngelx1 recorded a cover of This Day Aria. She has a great voice, and her version sounds awesome. Give it a listen, I'm sure you'll enjoy it.
