It is unlawful, of course, if it's done to make a profit. As long as mp3s aren't acquired and sold in CDs by people to make a profit, it should be fine for people to get them for their own personal use. Music is something that should be shared through the world to everyone. Music is something that comes from the soul. In the past, artists would work for many years to become known as a musician, and only those who loved music made it, though these days music is becoming more something that makes people rich and famous rather than something that will earn recognition for their beautiful art and talent.

Napster allows those making music for music's sake to get past all the hype and share what they love. That is what it is all about, but a lot of it has been lost. Music should be able to be traded through Napster. It gives people a chance to sample songs before buying CDs, which are very expensive, and it allows people to have the songs that they normally wouldn't buy because of cost.
