(This was essentially the conversation about file formats referenced here.
There are some minor reasons. The first is the zealotry of Apple fanboys that I wrote about in one of my very first posts. Another is that the iTunes Music Store encourages the culture of purchasing singles. I have zero interest in buying music in any increment less than an album, and I fear that digital music stores are pushing us further towards an era when the only music that gets published is pop and hip-hop “hits” churned out by the labels’ factories.
I would never consider buying music in the form of a file that has been compressed by a lossy algorithm, unless it was to somehow tide me over until I could buy the real thing. My understanding is that it is now possible to purchase lossless versions of at least some material, although you pay a premium to do so. I would also be unwilling to buy a license to use music in some specific ways. If I am giving the label money for it, I will play it wherever I please. Again, I believe that iTunes is going to scrap its anything-but FairPlay scheme in the very near future.
Even with lossless, non-DRM-ed files there remain serious issues with the music actually being useful, and this is the real reason that I will not be a customer anytime soon. The AAC and ALAC formats used by iTunes are indeed industry standards, and they are technically superior to the traditional MP3 format. However, interoperability is much more important than encoding quality to me. These standards remain encumbered by patent, and Apple has made it quite difficult for any other systems to work with files purchased from iTunes. If you think that it is not intentional that the iPod is the only digital music player capable of playing iTunes content, then I have a bridge to sell you. For some reason the same people that (rightly) complain about Microsoft trying to push OOXML over OpenDocument have no problem with this.
There are four primary ways that I need to be able to play the music that I own. The first is on a data CD in my vehicle. The second is in cmus on my server at home. The third is through the Jinzora -> MPD -> mpg123 stack at work. The fourth is through Exaile on my laptop. Of these, not a single one will be able to read iTunes files with FairPlay. A few can be made to work with DRM-less iTunes files, but two definitely cannot. Even applications to convert files from the iTunes format to something more universal are virtually nonexistent due to Apple’s enforcement of their intellectual property rights.
Although I generally prefer players that I can just point to a directory over those that force me to allow them to manage a music “library”, I might be interested in trying out the iTunes media player software if Apple decided to make it available for my operating system. They will not do so, of course, because it is competition against their own OS X product. I tried to use the iTunes Music Store as research for this project, and apparently they have even made it so that this is not possible without installing the software that they will not make available for me.
For now and the foreseeable future I will continue buying my music on physical media, ripping a FLAC copy for archival and an MP3 copy for easy transport between the different places that I listen to music, and having everything just work. I realize that I am a crotchety young man, but I reserve the right to allow this technology to pass me by. I also realize that many of the things that I dislike about iTMS were forced on Apple by the record labels, and that many other legitimate digital resalers have similar issues. Still, others like Magnatune seem to have gotten it right.
