What bit rate is used to encode the MP3+G tracks?

Our MP3+G tracks are currently encoded at 128kbps, however, we are in the process of updating all our tracks to be available at 320kbps.

Due to the large number of tracks we have to process we expect to offer 320kbps exclusively from July/August 2011 onwards.

Unfortunately it won't be possible to offer 320kbps files on request during the upgrade process.
