Self explanatory
Actually the iTunes stores only sells songs in AAC format (much better than mp3). To purchase mp3’s go to the Wallmart, MTV and Realmusic sites, all of which have only sold a fraction of the songs that the iTunes store has (which might change now that they are allowed to sell songs without built in DRM).
If your contention is that nobody pays for music that one can download for free, I would submit that the fact that the iTunes store has sold over a billion dollars in songs since it has started proves the fallacy of your supposition.
What you’re really saying is that you feel “stealing” is better.
