Side question: why did you name the application Joplin? (My hometown is Joplin, MO and I'm curious if you're also from or living there.) My other two guesses for its etymology are Janis Joplin and Scott Joplin.
Also, though Scott Joplin's ragtime musical style has a lot in common with some very informal music, his own approach was more educated, sophisticated, and precise. Every note was in its place for a reason, and he was known to prefer his pieces to be performed exactly as written. So you could say that compared to the people who came before him, his notes were more organized.
