Well, it doesn't look like there are any new songs on the Wicked soundtrack
Wicked: The Soundtrack will include the 11 songs from Act One of the stage show

Wicked apparently saw all of its fellow musical-to-movie adaptations adding original songs as Oscar bait and said, “I’m not that girl.” Universal just announced the soundtrack for the upcoming film, and, per Variety, it contains all 11 songs from Act One of the stage show, but—for all intents and purposes—only those 11 songs. This is a marked change from movie-musicals’ recent practice of slipping a new song or two into the score to become eligible for the Best Original Song Oscar. The Color Purple had two in “Keep It Movin” and “Superpower (I)”. Mean Girls put theirs in the credits with “Not My Fault” (featuring Megan Thee Stallion). Even the 2o12 adaptation of Les Misérables dared to add the original song “Suddenly” to one of the most iconic scores of all time. (The song was nominated for the Oscar, but didn’t win.)
That all being said, a preview of Wicked: The Soundtrack on Apple Music does contain commentary from original composer Stephen Schwartz and a song titled “Ozdust Duet” credited to The Wicked Orchestra. This is presumably an instrumental that wouldn’t be submitted for Best Original Song, and very well might be a part of the original stage show. It also isn’t currently listed anywhere on the soundtrack’s official site.
