a brief discussion of digital music

...Apple uses some sort of proprietary junk so you have to have Itunes or an apple product to listen to them...

This is a common misconceptions that is simply not true.
These days, there are quite a few different file formats for digital audio. For converting music you already own, the most common is MP3, and almost any digital music player you buy today will support MP3, the most notable exception being some Sony players. (yes, an iPod will play MP3 files). There are several other "open" audio formats, that offer various advantages over MP3, these include things like Ogg-vorbis and AAC, which offer higher quality for the same file size, and things like FLAC, which offers full CD-quality, but at the cost of a significantly larger file size.
A note about AAC, cause this is where a lot of the confusion about the iPod comes from. It is comonly (mis)understood that AAC stands for Apple Audio Codec, and is propriatary to apple and the ipod. This is untrue. AAC is the Advanced Audio Codec, and it is a part of the MPEG-4 standard set (MP3 is part of the MPEG-3 standard set), so it's really just the next generation MP3 standard, from the same standards body that gave us MP3. At the moment, the iPod is one of the few digital music players that supports AAC, but that is changing.
There are also several propriatary formats around for music, these include ATRAC (Sony), WMA (although it's microsoft, it's not truly an open specification), and Protected-AAC (Apple uses a propriatary version of AAC for songs bought through the iTunes music store). All three of these formats use some sort of Digital Rights Management(DRM) in order to prevent you from sending copies of music you purchased online to any or all of your friends.
This is where you realy have to make a choice. if you buy a sony ATRAC based player, you can only buy online at the sony store. If you buy an iPod, you can only buy music online from the iTunes store. If you buy a WMA player, you can only buy from stores that support WMA (which includes most of the online music stores except those previously mentioned). WMA based players also allow a subscription based model, where you pay a flat monthly fee to download as much music as you want. Keep in mind though that with these services, as soon as you stop paying, you loose access to all the music you have already downloaded.
The final thing to look at is what you are allowed to do with music you have purchased. As far as I know, iTunes is the ONLY service that will allow you to burn your music to a normal audio CD if you want to play it in your car/home stereo/wherever.
This got a little longer than I intended, but I hope it answers your questions.
oh, one more thing. None of the WMA based players support the Mac, so if you are a Mac user, your only choice is the iPod
