Quite a bizarre request
Well unfortunately discogs doesn't give you the date it was submitted. But, if you know the date a certain release was submitted, hopefully in early 2005 for your needs. Everything with an address with a number greater than that will have been submitted later than that. Understand?
Ex
http://www.discogs.com/release/34286 was submitted way after http://www.discogs.com/release/48
for this though you need to know the submission date of at least one release
By the way.......Why?
