A client update was released with these changes:
A few changes have been deployed to the Sovereign Shop:
We have started contracting with a few musicians to have them rearrange the original MIDI music for the game. In today's update are a couple of tracks re-done by Nadia Wheaton. You may notice that the music in dungeons, and one of the tracks in your house have been updated. We are continuing to get the rest of the music done and will have more related updates in the future.
