Problem: Playing any list of songs works, but as I click on applications or menus, the tune will temp pause and then start up again. It does not skip, per say, but it has a similar sound. I was using this same setup fine, but had to replace my internal hard drive (too small) and restore from backups. Then the problem started.
I have itunes 2.0.3 running on PB Firewire (OS 9.2.2) and the application is on the internal drive. The music is on an external VST Firewire drive.
