It really depends if you hate the High School Musical series or not but you can't deny it's catchy! This album which is the official soundtrack of the movie is designed for the younger audience as the Disney logo suggests. Although you will find many older viewers singing and dancing to the songs.
The soundtrack consists of a wide range of genres of music and like the songs in the previous installments: High School Musical and High School Musical 2, are quite simple and cheesy.
You may have hated the movie but most will enjoy the songs. Listen to it a few times and you'll be hooked!
