So Phil my main points were...   Discogs is flagrantly breaching songwriter's rights by giving out wrong information, irrespective of the cover information. Its software is autogenerating pages which Google prominently heads "Composition By", (instead of recorded by) with some piece of spurious information attached, picked up by its software. This means that it is stated as fact when you Google a song and people see that, and expect that the statement is true.    It creates multiple versions of the same song, with the song often being given a spurious date of initial recording - as the software is frequently unable to see that there is another earlier recording of the work. The separate issue is over cover errors and reproducing these when the errors have been corrected in copyright databases or subsequent pressings. Again this can lead to the software creating separate false 'composition by' pages crediting a writer or performer who had nothing to do with that work, which is breaching the copyright owners rights by creating fresh false information. That is why I say that Discogs is not a reliable source of information on songs, and should be treated with caution. There are thousands of songs that will be wrongly linked.
