Genius Question regarding classical music (or meta-data in general)

Question

OK - I have a fairly large library and probably 50% of it has meta-data that when pulled up automatically I leave (this is for the bulk, but not all of non-classical genres) as is post import and/or purchase from itunes. Now, here is the enchilada:
I am a big classical music listener and m constantly tweaking my library to make it as easy as possible to organize classical music - I still don't have it perfected as there isn't a standard - there are many standards and many are based on how you want to prioritize/search for things: I use composer as the "main" field to search(I have it as Mozart, Wolfgang Amadeus as opposed to just Mozart or Wolfgang Amadeus Mozart) and then I also search by Artist as a secondary way which is fine should I want to focus on a conductor or a string quartet, etc.
Now, there are basically three options that most folks will use with classical meta-data:
1. If purchased from iTunes, leave it as is
2. If pulled from CDDB, leave it as is
3. My methodology: I do both 1 & 2 and more than 95% of the time I have to tweak the way it looks.
Assuming all of this is common amongst the 65,000,000 iTunes users, I would love to know how Genius works with this - I uploaded to he Genius Cloud last night my library. How does Genius look at the same album which may have either simple or significant meta-data discrepencies/changes vs. the way it is in the iTunes system? Have I lost anyone in my rambling??
Thanks,
Steve

Answer 1

Based on what I have been seeing over at the Macworld forums, Genius does not play too well with classical music and the situation is really bad if the user modifies any fields to their liking. Using the ISRC code would make more sense, as it is something the user cannot modify and to rely on user-definable fields would result in many libraries being crippled in terms of the new feature.
In terms of the metadata, there are two composer fields: Composer and Sort Composer. You would place “Mozart” or “Wolfgang Amadeus Mozart” in the composer tag and “Mozart, Wolfgang Amadeus” in the Sort Composer tag to force the proper sorting order.
