Using data from the musixmatch API, I have created a tool that shows what words musical artists use most in their lyrics. It uses a combination of jQuery and D3 libraries to work as a single-page “app”. Try it here.
The web “app” works by finding the artist you search for, and running through every lyric it can find by the artist to develop a lexicon. Once that lexicon is built, you can click on the box that is created to view statistics about their most-used words.
You can also view the most-used overall by clicking the “All Artists” button.
