The whole IP v. non-IP debate is mired in bad nomenclature -- it's all IP.
The two sides are better called:
- *pre-existing* IP (that has appeared in a movie, TV show, or some other context), and,
- *newly-created* IP.
Both have their pros and cons.
The *pre-existing* IP is being recontextualized for a new attraction. The recontextualization could be "shoe horned in" or "rammed down our throats." In this case, it's used simply because it's popular. It's a tangent to a story that doesn't fit. This can happen when your new show needs a certain theme, e.g., you want two people singing about how their friendship brings them joy and makes them a family.... and all you got is
Friend In Me, which is oversued, or,
Friend Like Me, which really isn't the message you want (since it's not about two people singing about the joy of their friendship).
On the other hand, it could be done quite well when the original context fits the new context. "I See the Light" fits very well for any context of a new, budding romance.
And so, it is the newly-created music that has a much better chance of getting across the theme and message one wants to convey. It can be tailored specifically for the context. BUT... it's brand new. And is the song itself... *good*? A new song hasn't had the chance to be tested with crowds. It could be wildly popular. It could be a dud.
And that's the advantage of the pre-existing IP... you already know it's popular. Put a bunch of popular songs in a show and you're much more likely to get a popular show.
As time has passed, Disney has amassed a pretty hefty 'Disney songbook' of hits that it didn't have 20, 30, or 40 years ago. People want the band on the stage to play their famous hits, not their new songs... that's why the came to their concert. And so it's what many people expect. And it's what management encourages for that sweet synergistic merchandising franchise.
Luminous was made with pre-existing and new music. And did some clever things like using only the lick from
Into the Unknown, without any of its lyrics. It unfortunately overused the two 'friends songs.'
Anyhoo, I'll leave you all with a mind-blowing thought: Epcot Forever recontextualized the music from previous attractions, so, it rammed IP down our throats!!
