Awesome. Thanks. I figured other musicians had probably worked out something but I couldn't find it. Glad I asked before spending a bunch of time trying to create a new system.
First off, I'm not sure if this violates the copyright policy, so I used a public domain Christmas song.
At first I was just gonna add some reminders, but realized for some songs more can be given.
I suspect it'd be against the policy to post these charts if they're copyrighted tunes, right...
