Disney is working on some more musicals at the moment...so we just have to wait.
The international success of HSM has shown not only Disney but many other countries how popular Musicals can get. I can not wait for more from Disney though. Isn't
Enchanted suppose to be a musical? (Sadly most to come do not look like Musicals)
I am sure we can expect Rapunzal to have a soundtrack and score.
