Plot hole: There's no way that Eddie and Nana left the flooded theater without getting a single drop of water on them. The water flooded up to the ceiling and there's no other way to exit besides the front doors, and Moon's secret exit, which also floods. They do not leave through either way.
Plot hole: After Moon gives his first pep talk about working harder than ever to the contestants, Eddie asks loudly "What about the hundred grand?!" in earshot of most of the contestants. The contestants (especially Johnny or Pete) would have heard that question and started asking their own. (00:24:50)
Answer: It would have to do with paying royalties to the artists if the songs were included on the soundtrack album. The artists would be paid a one-time flat fee for their songs to be used in the movies or the trailers, but for albums being sold would mean some of the profits would have go to the artists. The movie studio can make just as much on the soundtrack album without certain songs being included. Regarding the title, it may be the artist wanted it changed for some reason, or the filmmakers felt it didn't fit in.
