Is anyone using iTunes to catalog live concert releases? The tags available with AAC encoding are rather limited ... it would be great to add date/venue/label etc. information to tracks but the only workaround that occurs is to use the "comment" field for recording dates and then perhaps "composer" (rarely used for popular music/rock/blues) for label and catalog number. Any other suggestions?

Thanks!

Here's what I came up with:

I record the date and venue info in the Album field, for instance:

1973-09-03 Madison Square Garden, New York, NY

Any other relevant stuff goes in the Comment field.

Album art and notes get manually placed in the directory after ITunes creates it.
