We have made another very small adjustment to our auto radio stations.
They now drop meta data for commercials so that they don't interrupt things like Libre.fm and Last.fm where the commercials would trend becuase they play so often.
We have also made a small change to the way the audio gain is set, we previously normalized the audio but we are now normalizing it with parameters which should give a better response.
Some audio tracks were not complely stable when using the old system and slight fluctuations in volume might have been noticed.
