I corrected most of set. Much of the composer credits are in text in the included book, which reveal more than the name then in lists. Same can be said for artist, which I have not corrected. (i.e. Flat & Scruggs & the Clinch Mountain Boys). Song titles often have parenthesis (round brackets) as part of title. i.e. 15-23 “Free Me (From The Blues)” So I think the use of (square) brackets for non title info. makes them separate from titles. i.e. [take 1], [live version], etc.
