Yes you're right. Out of interest what program do you use to rip your CDs? I use Ashampoo Music Studio and although good in some ways, doesn't extract the composer data correctly, hence I had to re-tag as described above to get the albums showing under 'Composer'.

PS: Have now tried Exact Audio Copy which does a more complete job of extracting the metadata and is more configurable.
