True, but we're talking about decoding compressed audio. Most codecs allow speed vs. quality tradeoffs in decoding compressed audio and feeding the uncompressed "720 kbit/s stream" to the burn engine.

On top of that, get an audio program that increases the bitrate of your music. DMBpowerAmp, I think it's called? I had it a while back, I can't seem to remember the name properly, so Google searches are kinda futile. But yeah, use that and then slow the burning speed down, and I'm sure it'll be incredible.
I wonder, though, since most of us probably use iPods (maybe?) in our cars, is there anyway to tweak the iPod settings so that better sound is heard? Or is it already giving the best sound possible?

You learn something new every day. I thought some codecs had speed/quality trade offs in encoding but not in decoding, what codec are you using?
I just copy the mp3 files directly onto the CD and play them back on the standard BMW CD. at 1x decoding speed all mp3 decoders are wonderful including the BMW one. They start to break down when you asked them to decode at higher speeds - speeds that they were not designed for in the first place.

My understanding is that the music in CD is a simple digital data. Digital data can simply be read if its not corrupted ( That means the machine understands the bits) I am not sure how there can be some low quality or high quality data (low quality bits and high quality bits). Its like having DVD burned at high speed with low quality pictures and DVDs burned at low speed has high quality pictures which is not possible at all... Its not tape to deteriorate over time JMHO

Bottom line. The E60 audio system does support MP3. You should all do what I do - burn data (not audio) CDs that contain MP3s and let the BMW audio system take care of the MP3 decompression. The bonus of this approach is that you will be able to fit 10x as much music as on an audio CD as well. If your BMW CD player does not support data CDs with MP3 files on them get a software update.
