Some of the unblocked music sites at school include the MTV and Youtube. They do have a great number of music videos which can be watched for free. Music sites with explicit music videos can be hazardous to the schooling environment and the development of the students.
I usually get on musicmp3.ru but it just recently got blocked in my school , but it might work for you guys , I am not sure . it is awesome , the best website ever , it has every song from every album from every single artist . its absolutely amazing (: hope I helped .
and the only above comment websites that work for me are the music choice , and the loudmusic247 thanks you guys (:
