Max..Like most, I support the decision to remove the 'offending' songs. But please, don't gratify them by linking the remnant of the DT entry to THEIR site! Just leave a message saying something like "Can probably be found at other sites using standard search engines."
Still and also - how do we know that the DT files are the same as the "Compositions" they refer to. Can't I take a song (from the public domain - even a published version), change a word or two, rearrange it for kazoo, copyright and publish it? It's only the specific arrangement that's copyrighted, right? Anything else is just a new 'author's' interpretation.
