An MP3 file may be different in substance from a solid piece of material in a store.
But entertain this scenario -- you walk into the music section at Barnes and Noble, steal a CD of Death Magnetic, then copy it on your computer and give it out to whoever asks.
How is that different?
Well, let's consider the basic scenario, so to speak: Artist X records music, then they create physical copies (cd's, records, tapes, etc.) and/or digital copies (wav's, mp3's, or whatever) of that music. Then they release a number of physical and/or digital copies of that music. Consumer Y buys one of X's cd's. So far, Y has done nothing wrong. But let us suppose consumer Y burns his copy of Artist X's cd or rips an mp3 from that copy and then gives person Z that cd or mp3. It is not obvious (at least not to me) that Y has done something wrong in this case. He has paid for a product and he has managed to virtually reproduce the product (if it's a cd, he hasn't really reproduced what he bought unless he reproduces the case, the booklet, the cd art, etc; but, in the case of a digital sound file, which many artists release, he can easily reproduce an identical product), and he gives that reproduction to somebody else. Those actions in themselves do not seem obviously wrong. Now, if he uses deception to sell the reproduction for more than it's worth or if he tells people that he has created that music, then maybe the case is different, but let's focus on the actions per se that I have described.
A few questions, related to my above observations, that might produce further discussion: Is there a difference between, say, letting my friend listen to the cd I bought from X and giving him a burnt copy of the cd for him to keep? What about if I set up a website where he can access the music (however he pleases obviously, via phone or computer or whatever else he can use to access a website) whenver he pleases and he accesses it whenever he pleases, but he never actually obtains a copy of the music? What if I build a chair, give it to you, and you are able to (either, e.g., from your own ingenuity or because you have a machine that will do it or you learn how to from a book or someone else) reproduce the chair identically, i.e., you use the same type of wood, you create the same design, color it the same way, make sure it feels the same, etc... would it be wrong for you to give that reproduced chair to somebody?
