I'd say it would be best to maybe do a yearly update if you're going to post the WHOLE list. Most people here have upwards of a thousand CD's, so the thread would get insane if lists were getting reposted with every purchase.
10/18 - King Diamond
10/24 - Pallbearer
11/01 - Suffocation
11/30 - Devin Townsend
12/06 - Distant Worlds: the Music of Final Fantasy
