...until Djeinus shared an awesome version of the Title Theme with me! (See what I did there?) Seriously, though, Djeinus shared sheet music for the Title Theme, and it's not just sheet music. It's also guitar tab. It's well worth checking out, and you can listen to a midi version here. It's wonderfully accurate and a ton of fun to play.
Djeinus also has a DA page with lots of great artwork. Clearly this is a person with many talents!
Thank for sharing, Djeinus!
