I am not even sure where to being. First, I doubt that you even have a wife, nor that you use iTunes for anything other than being able to say you have it installed. You have an iTunes account setup, you have your payment information already setup. Then I find the album and buy it. At most, I have to type my password again. Done. Oh, about running SoundConversion? All of iTunes music is now DRM free. All I have to do is tell it to export to MP3 with a right click on the album, from iTunes. And the artists (and distributers) get paid.
TPB, find the album, hope it isn't a honeypot for anti piracy, a joke with the wrong music, or an old link no one is uploading anymore. Then download it. And no one gets paid.
Sorry, TPB is not all that much easier, and in fact, I would say with the unreliability of some of the non-popular music/movies, it is worse.
