sample argument of definition

Is downlaoding music hurting the singers and bands by taking money in their pocket or is it a way to help them put money in their pocket by exposing their music to other people? I think that this is a good definition because you can make a claim to this statement like downloading music does not hurt the singers or bands or downloading music does hurt the singers or bands. You can make a reason with this information like it noes not hurt them because it instead spreads their music to people who possibly would never listen to them, which then can make people want more and they can buy cds and go to the concert. Or they can say that It does not help them because it does not force people to go out and buy the cd. For the warrent it can be somthing like bands usually gain more money and popularity by allowing people to download their music and the same for the other side.
