Thanks Joe you pretty much get it. I'm not criticising the site! It's just there are conflicting 'truths' about album credits.   Many long gone issues about who wrote a song could come back to haunt.   What you have to remember as well is that the official track details for the release as licensed by the copyright societies could be entirely different to what appeared on the covers or labels.   

Take this example: Artist Joe. E. Hamilton, title track of the album 'Sing Me A Good Old Country Song' - correctly licensed as Stewart Ross Sylvantone Music and the album listing with MCPS states that - but it originally went out as being to Slater/Henley who had written a different song called 'Sing Me (an old fashioned song). So the song being referred to is not even the one on the album!

The funny thing about that one, is that my father got sent a copy of the LP to review for the country press and found when he played it that the title track was his own song, wrongly credited to the writers of this other completely different song!   

But you see the problem with transferring old credits! The download version has been corrected. But I think a good half of the songs that were written by my father and many thousands of other writers have had errors and misprints along the way.
