Tag fields comparison

Greetings.

Recently i noticed that albums from digital stores already have some embedded metadata in downloaded files. Somewhere its more, somewhere less, but anyway it is.

And when i start to compare “existing metadata vs MB” i got a thought - is it possible to utilize some Picard’s functional for this?

For example i need to compare composers credits, but so far as i understand Picard does a comparison “string vs string”, but since there are several composers in one string, separated by “;” - it cant compare, say, “block vs block”. Also composers sorted in different order.

Would be nice if Picard could sort credits before compare them “block to block” and then colorize (with red for example) strings that differ.

So is it possible do somehow now?
