Actually, if it remains keyed to a musical act, I think Aerosmith is a pretty solid choice. My "teen years" were in the 70s, and although I was not necessarily a huge fan, Aerosmith was an ingrained part of my popular culture. For me, and others of my generation, it's kind of a cool nostalgia trip, and the crazy, brightly colored Hollywood images flashing past in the dark are kind of like a different kind of "trip" from that era. But the band is still "edgy" enough, and still gets radio play on "alt rock" stations, to appeal to younger generations. There are not a lot of other bands that would have this kind of cross-generational appeal. The fact of the matter is that the ride has never really fit thematically into the surrounding 1930s/40s Hollywood feel. To do that, the music should be something like Benny Goodman's "Sing, Sing, Sing" - but as much as I love classic big band music, it just doesn't "go" especially well with a high-speed rollercoaster experience. You might be able to push it to the early years of rock and roll (i.e. "Rock Around the Clock"), which would still fit with the current interior theming, but it would be a pure "nostalgia" experience. I say leave it just as it is - at least until a final decision on what happens to the old Animation Courtyard area is made and then possibly re-theme it to whatever is going in there.
