Disney's trying to do a cheap, "value-oriented", "de-risked" American Idol reboot. What could go wrong???
As for the possibility of theme park tie-ins... I could deal with RnRC without Aerosmith, as long as it's still **rock and roll**. Adding a bunch of bubble gum pop or country singers to it would seriously decrease my desire to ride to the point where I wouldn't care if I rode it or not.
This actually sounds kind of great.
Maybe not American Idol, but a new group every 3 months would be welcome. This could actually be really easy to implement too- all they would need to do is shoot a new preshow video (replace the IMax screen with 4k projection or an OLED screen) with the group of the moment and have someone cut together 3-4 on-ride music tracks. Or heck, have the "starring" artist change over every two hours or so. As long as the front signage (light board) preshow, and music tracks were synced up people would get it. Or if it has to be American Idol, maybe they could even have park guests vote on the next hour's artists via an app or Twitter or something.
