This is a working list. There may be some errors and there are many missing entries. The entries highlighted in yellow are duplicates and need to be confirmed. 

A special thanks to readers like Phillip A., Martin K., Jacob L., Connie C., and especially Raymond D., for providing some missing entries. And also to Discogs from where I got the bulk of this information.

If you have a missing entry and want to contribute, please message me.
