Welcome to Grateful Data. Grateful Data isn't programming code (per se), but an online tutorial about data acquisition, cleaning and enriching, using publicly accessible data on the band the Grateful Dead as examples.
To get started, you will need a program called OpenRefine. If you don't already have it, I would recommend downloading and installing the current stable version. OpenRefine's website, with download links and installation instructions, is here.

More information is available here, but the short version is treat it like a tape-trader: share and share alike, but not for commercial purposes, and always with appropriate credit. If you want to build on what I've done, fantastic, but only under the same license.
A Note About Data Licenses
Because of this, I will provide instructions on how to acquire ASCAP's data, but will not make the data available on this Git.
