The Shovel Knight series has some of the best music ever, IMO!! I'd be happy to see any song added to the list of sheet music here. There are a few that I particularly like, though:
A Thousand Leagues Below. https://youtu.be/ynLNyLH8MbY
La Danse Macabre. https://youtu.be/UDJMKv2Old8
In the Halls of the Usurper. https://youtu.be/4uOuLH5xKVc
The Defender. https://youtu.be/7-QYysgasoQ
If there is any other place to find Shovel Knight sheet music, I am unaware of it.
Thanks!
