Guess Case

From MusicBrainz Wiki

Guess case changes the capitalization of titles to be closer to our language guidelines. While in most situations it is not perfect and the result will still need some human corrections, it can still save a lot of time.

Modes

These are the currently available Guess Case modes:

English
Tries to make titles follow the English language guidelines.
Sentence
This method capitalizes the first word of a sentence, but all the following words of the sentence are kept lowercase. This is close to the guidelines for a lot of non-English languages, but you should still look out for proper nouns and any other differences indicated in the appropriate language guideline.
French
This method is very similar to the Sentence one, but a space is inserted before semicolons, colons, exclamation marks and question marks (;:!?) and text inside guillemets is padded with spaces too (« text »).
