Since it's the weekend, time zone differences and work pattens prevented me posting before now.
I have some slightly bad news, the music fix is not in the next to release patch, which some have assumed due to supports comments - the latest patch is already in testing.
I know this may disappoint some of you, however I don't want you disappointed when it arrives.
While many of you are assuming it's everyone who is suffering this missing music issue, it's not quite that simple or widespread [ I know many on the forums are affected]
The team
are investigating, however they need more people to report and supply detailed set up / software / hardware information - via support.
If the team can not reproduce the issue, consistently, and no, it's not a simple case of installing the DLC - then it makes fixing it even more tricky.. so please send reports directly to support if you are affected:

The more reports and information they get the better!
