I don't like Musicmatch or iTunes b/c when it puts something in the "comments" field of the ID3 tag. When you try to burn with Nero, the tags are all screwed up.
I still prefer iTunes since the comments it puts in are visible in the ID3 tag via Explorer. Musicmatch's comments are invisible, but if I "clear" the tag, Nero reads the tags properly.
And 98SE, for earlier iTunes versions it's Edit/Preferences/Importing. EDIT... Oops, didn't fully read your post!
