A difficult one historical truth versus historical truth. The historical truth that you are reproducing an image and facts about a release with its credits. But the credits may have been misprinted, and were in many cases wrong due to simple errors. So as a songwriter who knows the truth. when you own the song.. and had the product officially changed - do you leave it in error when Google will pick up the error and the song be linked to a wrong writer or do you put in the corrected credit in the appropriate space? Discogs is this on-line archive of Album/ single images and information on releases plus items for sale and there are other similar sites.
