Dear Martyn Jago, Congratulations to the Lilypond support included in the new Org version 7.6! For someone who uses both Org-mode and Lilypond anyway (like me :), this is great to have!
Some brief comments. Support for additional languages like Lilypond and also awk should be celebrated by including them in the list of languages in the documentation (http://orgmode.org/org.html#Languages). I first had to load dot support (because you are calling org-babel-expand-body:dot). If you want to also attract musicians (without Org-programming experience themselves) it might be a good idea to very clearly document this dependency (or to remove it). Thank you!
