Comment Depends too much on the song (Score 1) 567
And since when is Billy Jean representative of music in general? It is a song with typical radio production and will not gain as much as music with higher production values might from higher bitrate.
Having conducted a double blind test with some friends I got wastly different results depending on the song.. Everyone could tell the difference between 128kbit mp3:s and 320 kbit mp3:s when listening to orchestral music, but noone could tell the difference between 320kbit and the actual CD. When listening to "Ace of Spades" with Motörhead noone could tell the difference between 128 and 320kbit.
As a sidenote, when we tested noone could tell the difference between the cheapest possible CD-player and a semi-expensive Marantz unit either. Or between cheap and expensive cables...
