I hadn't noticed this discrepancy until Ron pointed it out. On Racks and Tags, I have 1665 "albums".

On OCD, I have 1907 discs. As VendenBos suggested, this is due mainly to having a large number Box Sets, such as operas. I only call multiple CDs a Box Set if they represent one work on more than one disc like an opera or large choral work. If it is a box or collection with various different works, I prefer to keep them as separate items. The term "album" in R&T is therefore pretty meaningless for me.

Also, it is strange to read that I have 29924 "songs". Only about a third of my collection is rock and pop, so most items are not "songs". It would be be more accurate to use a neutral term such as "tracks".
