I have a bunch of songs (100+) that I downloaded, burned to CD, and then put back on my computer, including a few songs on this spreadsheet.
I have no idea what all of the highlighting is, but I assume it means ones you've already found.
I might make a torrent of all of them or something, if there's any interest. Most of the tracks aren't labeled since the were burned to CD first. Since they're only CD quality you might not want them, but at least it's better than nothing.
