If your school has these sites and their downloads blocked, that means you are not supposed to do it on their network.
Bottom line... obey the rules and get over it. Downloading over these sites is 99.99% illegal anyway, so you shouldn't even be bothering with it.
Spring for the album, or buy the songs you like through iTunes or one of the many other legit online music stores.
