blueplaylist.com
you can try sites like VEVO
I recommend music is my soul website. They have a huge selection of music worksheets to choose from. You can get them to use on your school assignments.
It really varies per school, as the protection + sites blocked are different in every school (unless you use a shared one) I have added the related link to a music site that works in my school.

You can find choir sheet music for a variety of songs at music stores, online sheet music websites, and through music publishers.
You could find a reputable music school in your area by asking the local music teacher at any school. You could also check through the music programs at local universities and/or colleges.
One can watch the latest music videos through popular video hosting websites online. YouTube, Vimeo, and VEVO are all great websites to view music videos.
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.
Servers do not block music, it is rather websites and ports that are being filtered. Do some searching, you should be able to find a free mp3 download site over the Internet that can be accessed.
There are websites, such as Jamendo (See links below), through which musicians share their music for free. Commercial music is only available to buy and taking it without paying for it is theft.
