Woah, now that I read this, what's with all the hatin' on the iTunes Plus music? AAC
is superior to MP3 in virtually every way. MP3 can be great if it is encoded using modern technology (e.g. a modern LAME encoder -- think Max, for you Apple users) but from every technical perspective AAC is superior.
But in practice, here is how it breaks down:
Winner
iTunes Plus Music. With AAC encoding and a very respectable bitrate this is the best music you can get. Encoding is top notch and quality is stellar. You're not going to be telling it apart from the CD. The only reason why I sometimes choose Amazon over this format is that the DVD player in my car doesn't support AAC, which means I would have to re-encode this music in MP3 format if I wanted to play it on an MP3 DVD, and in that case I
would be losing out.
Runner-up
Amazon's MP3s are very high quality and they sound wonderful. In practice, despite technical differences, at a bit rate of 256 you won't be noticing much difference between this music and the iTunes Plus offerings. As such, if you want MP3 rather than AAC (which there is absolutely no reason to want unless you have equipment that doesn't support AAC -- equipment going forward will support it) Amazon is the way to go. You can save $.10 on some songs as well and occasionally Amazon has some really cool deals (you'll miss them unless you pay close attention, though). The interface is much more frustrating, but for someone who can figure out how to participate in a forum, this is no great challenge. Once you download their crappy downloader it does most of the annoying work for you.
Fair
Regular ol' DRM-protected iTunes music with a bit rate of 128. Many elements of the music industry maintain that this music is virtually indistinguishable from the CD, but I disagree -- and I'm not alone. Play this next to an iTunes Plus song, or something from the Amazon MP3 store, and you'll notice the difference (well, as long as you're listening to something that actually contains music). Five computers is quite generous and if you are responsible this shouldn't be an issue, but I
hate DRM and avoid this in almost every case.
But let's be clear about something... it isn't Apple's choice to decide what isn't offered in the iTunes Plus format. They want to use that format. The choice belongs to the labels which, as mentioned earlier, are very cautious when it comes to Apple and the music store. They want to create an environment with multiple players so they remain in as much control as possible. This isn't exactly a good thing for us in this case.
