Well, I had said that the thing to do would be to integrate a small slice of a music streaming service, like Spotify, into the Universal app; they’d cover the licensing fees, and in return, Universal would compensate Spotify or whomever. That could also open the door up to have songs rotated out every quarter or so to avoid what I call “Black Eyed Peas Syndrome”.
Then, you’d have 1000 songs available; 100 songs from 10 genres, with the “secret song” keypad replacing the current menu setup entirely.
I think it’d be cool as well if you found songs that worked well with the way the ride is set up; for instance, I tried putting a POV of the current ride with “Year of the Cat”, the Al Stewart song, and I set it up such that the sax solo in that song starts right as you start down the lift hill, so that you not only get that solo, but just about the rest of the song as well. Stuff like that would make your music choice really matter, in my opinion.
