In several of my genres I probably have a third of the CDs released prior to 2007. I would suggest that only CDs released in the past 18 months be eligible. That would reduce the effort considerably. Some of these CDs were released in 1998 or 2002 or whatever and have probably been entered every year.

Is there a reason we couldn't use a release date (like the Grammys) as a cutoff period for submission?
