It's actually really simple once you do it once. I can crank songs out in about 5 minutes and then optimize them with a regular expression so they don't waste notes (since there's note spam prevention). but shhhh, it's against tos since it's macro.
The music macros will be no more soon enough though, replaced with a legitimate update for music scripts in lotro. Damnit, I'll have to redo the scripts :(
