The sites that are blocked will vary based on the settings the school has set up. Some good sites for listening to music are Pandora, LastFm, I Heart Radio, and Playlist.
Nothing , Stay In School !
There are some other unblocked music website like Clearly drunk, MySpace Music, Rdio, TuneIn, Gaana, Playlist Sound, Jango, PureVolume so on, which you can visit and enjoy free music at School.
If a whole category of sites are blocked it is usually with good reason, and attempting to evade the block will likely get you banned from the network. Familiarize yourself with your network's Terms of Service (or talk to your parents about their parental controls :P) and only contact ITS about asking for unblocking if the ToS does not seem to indicate usage of music sites is not permitted.
There are many ways in which one can find a link to the "Some Beach" music video. This includes video streaming sites such as YouTube and Vimeo, as well as music fan sites.
Kazaa is a free music downloading site, but i would not suggest using it. Downloading music off many sites such as that is illegal. If you want to get music i suggest buying the CD or buying it off iTunes. YoutubeMp3 is a great site to get music for free. All you have to do is look up the song you want on Youtube, then paste the link the YoutubeMp3 and it will convert it into a Mp3 for you to download. It works great!
