On the point of quality.
The emusic version, which I have, is V2 VBR, which is a good standard that you can play on good speakers and put on CD without it being too obvious it isn't the CD itself.
If I downloaded from itunes, I'd not only have DRM, but a file fucked around with, transcoded and compressed to some shit format so the sound quality is terrible anyway
Maybe I care too much about bitrate, for the one song it's no major disaster as I'll be buying the CD, but if I was to ever pay to download a whole album I'd feel fucking ripped off
If iiTunes gave you the option of downloading a good quality mp3, or had different prices say to download their standard one, an mp3, or a CD quality FLAC file I'd maybe use it

Oh, and don't forget: pretty soon, iTunes will be offering a choice - the 128 or a V0 Mp3, DRM free, so all will be well in the world again.

1. Don't be so sure. The file you're burning to the CD is only about 128 kb/s. all those super high and low frequencies have already been removed. You put that on a CD, your computer is making a wav in the background by filling in those empty spots with the unheard frequencies - you rip to mp3, it will just take the same out and you're back where you started.
If you really want to test such a theory out, all you'd have to do is take an mp3 of any bitrate, burn it to a CD, rip that track out at the same bitrate, burn that track to a CD, rip that track, and repeat the cycle maybe 10 times. If there's a loss of quality every time you do this, if it's only audible to a trained ear after one time, then after 10 times it should be obvious to all that the 10th track is not the same quality as the first. I haven't tried this, but have always wanted to. My extensive experience in the mp3 world tells me that there will be no change in quality.
2. Why is itunes doing this? Aren't they getting along just fine fucking the music buying public over? Why give them any sort of a choice?
(I buy itunes songs too, just the exclusive ones from the bands I follow - to date, I think I have bought 50 songs from them.)

You're saying there will, or won't be a loss in quality? If there is, then the algorithms they use for encoding are fucked up, because what I learned about them in 2000 tells me that as long as we are dealing with the same quality and encoder there should not be a loss. If you do find out where you read it, please post it.

MP3 is a lossy compression format - and as such will lose quality on repeated passes. See this wikipedia article for details.
Most other formats that produce relatively small files are also lossy e.g. ogg vorbis, aac, wma.
wav is lossless, but has far bigger files as a result of storing all of the samples.

kriscoverdale wrote:I'm not sure I fully follow what you're referring to here now - my assumption is that you are referring to repeatedly re-encoding a song in mp3. If so, I think it isn't simply a case that you get rid of the stuff you don't need the first time and then do nothing on repeated passes. Instead errors introduced on the first pass are then part of the input the 2nd time, which leads to bigger errors being fed into the 3rd pass etc. This is similar to what you can do with a photocopy - if you keep re-photocopying the copies that come out, the quality very quickly degrades. I've found an interesting discussion about exactly this topic here
If you're referring to reencoding an MP3 to a WAV, and then repeatedly using that, then yes you'd only lose the quality once in the encoding pass.

, whatevermort why would you want to pay for your music twice?regs. iTunes uses its own proprietary music format, yes, but I think that's why choice is good. If you only listen to stuff on an iPod nano, and want a smaller size format - because, God knows, you don't want to transcode anything, it sounds like watery ass - then iTunes can be a godsend. If you subscribe to emusic, or use another service, then brilliant, that's awesome as well - though, I can't stress enough, burning a song and then re-ripping it results in serious quality loss.
