Wow nice work, I haven't seen anything quite as well laid out for typical songwriter use. There are some good web apps for handling notation and composition but I haven't found anything as nice as what you just created for songwriters.
Thanks so much! Yeah, there are some great tools for composing, and some good stuff for individual features (RhymeZone, Hookpad, etc). I was surprised that I couldn't find anything quite in this category.
