Just installed 1.4, seems to be working well. What's happening your end?

Running iTunes 11.0.1 on 10.8.3 current DP/Beta on a 12-Core Mac Pro

I reinstalled the 1.4 but to no avail (followed the instructions step-by-step), the song notifications won’t show up (I checked the notification settings as well). 11.0.1 iTunes and OS 10.8.2.
