First thing I noticed is the audio quality seems to be absolutely horrible in this new version!
The following differences were VERY obvious on my sound system:
- iTunes seems to get confused with complicated songs, and songs where lots of instruments are playing at the same time to the point where even CD quality recordings drop to worse sounding than a 96kbs mp3, the same songs now sound better on youtube than on iTunes
- Despite disabling all the enhancements, the volume seems substantially reduced
- If I use another player such as Winamp beta for mac, the sound is fine again suggesting the new ITunes is the problem.
