MP3 bitrate

and if you can't hear the difference between 128kbps and 320kbps...

WHAT THE HELL IS WRONG WITH YOUR EARS!? >_>

If you can't hear the difference between MP3's and uncompressed WAV's (or lossless compression)
WHAT THE HELL IS WRONG WITH YOUR EARS!?

^ Than unless the music you use as source has nothing above the 16.000Hz range, there is something wrong with your ears.

[satan ahh lunn]

i listen to only 44Hz and 128kbps but burn them to cd at 320kbps

so...

^ 44Hz ? I think you mean 44.1KHz.

Anyway, MP3's (like discussed a bit up in the thread) cut off the range above 16KHz for higher compression rates. Only the very good compressors try and encode.
But then again (like discussed before) not much of the current 'music' is high quality anyway.
