Unless I'm missing something, this isn't quite true, or is at least
slightly misleading.

Probably because I didn't think we were talking about many to many here...

In the traditional case of Artist -> CD, the CD has the artist as a
column. And as we already have our artist object, we know its PK. So
all we have to do is:

SELECT cd_id
FROM   artist_cd
WERE   cd_id = ? 
AND    year = ?

Or is it too early in the morning?
