Unblock Music Websites On Chromebooks (Soundcloud, Spotify).

Our schools block every website they possibly can and I will not argue about that, but I do believe that blocking websites like Spotify and Soundcloud is just too far. As students, music helps us relax and when teacher grant permission to listen to music we need an app to do so. I understand that Pandora is unblocked but that is a radio station so you can not pick a song that you like, if you can not pick a song that you actually want to hear how do you expect to enjoy it? Please understand our needs, Thank You.
