Comment by TheJudge:
This has been raised in the mod forum for comment. For myself, I don't see any reason for a further category, as SHM-CDs are fully compatible with standard CD players. I'm aware that this creates an inconsistency with HDCD and SACD. We'll see what the consensus amongst the mods is.

Only just noticed that we don't yet have an "SHM-CD" option in the dropdown for "CD Type", we have "HDCD" and "SACD", any chance of adding "SHM-CD"?, as i think there will be many more to be added (i've added a few myself in the past)
