One key advantage of LAMP, in addition to its being free for its users, is the fact that any piece of music is in theory available on it because copyright law is more lax about broadcasting over analog transmissions, such as MIT Cable, than it is about digital transmissions such as those made over computer networks. For example, a person wanting to transmit a copy of "... Baby One More Time", written by Max Martin and performed by Britney Spears, could do it either with an analog transmission or a digital transmission. Using an analog transmission would only require permission from BMG, the publisher, whereas use of a digital transmission would require Spears's permission as well.
