I’m a computer science graduate student and am planning to do a project on popular American music from 1950-2010. Some information I plan to include that does not look like it’s already in the Whitburn spreadsheet would be key, whether there are any key changes in the song, and whether the song is original or a cover. I would be willing to freely share my results with anyone who is interested, but a major help for me would be getting a hold of the spreadsheet. If anyone knows where I can locate this spreadsheet I would be most grateful for their help. Thanks!
