As a thespian, I wasn't personally all that bothered by the frequency of songs. They tried to make this movie a lot more like a musical than some of their others, potentially because they had the incredible musical theatre performer Idina Menzel as an asset on their cast, and Jonathan who is seasoned musical theatre performer as well. Knowing these were two of the actors before I saw the movie meant that I approached it as a movie-musical and thus wasn't at all surprised; perhaps I would have felt differently if I went into it blind.
