I have made some music in GarageBand '09, and when I export it, there is some strange data in the ID3 tags. When I open the MP3 in VLC, and view the meta data, there is field called Description and it contains a long string of hex. Everything else is correct. Is this a hash or fingerprint of my song or what?
Thanks, can't upvote yet. So I assume that VLC does not use this information. Would I be correct then to assume that the song will sound differently if I play it in iTunes? – emkman – 2011-01-09T00:39:10.467
@emkman: If "Sound Check" is enabled in Preferences, yes. See this Apple page. (Regarding upvoting, see here)
