Musical theatre newbie needs help!

@EmsDad sorry for the late response but I was hoping you could clarify something from your last post. What is the difference between “an appropriate role from a show that has been on Broadway in the last 5 years” and the contemporary uptempo & ballad? Is it just that contemporary can mean anything after 1960 as opposed to the last 5 years? Also, what is the definition of “art song”? Right now my D is preparing for a summer program that requires 2 songs from the Golden Age (1 uptempo, 1 ballad), 2 contemporary songs (1 uptempo, 1 ballad), 1 non-MT pop song from the 50s/60s, 1non-MT pop song from the 70s/80s, and 1 “style” song (country, R&B, gospel, rap, etc.). Are these all songs she should keep in her rep book plus the additions from your list? Thanks in advance!
