I agree re NBN news theme music... I've never really liked any of the versions.
To this day I still don't get (and have wondered this ever since aggregation pretty much) WHY NBN refuses to use the network theme.
Anyway that is bound to change when the rebranding has been fully completed later this year.
Lately at the end of the 6pm bulletin, they've been referring to their next news bulletin as being during the 'Today' show from 5:30am
They either fail to realise or conveniently forget that they air the 5am Nine Early News bulletins.
Just yet another sign I guess that NBN News does not want to be seen as part of the network, despite the heavy reliance on network content.
