Android Media Notifications

[Plus18]

In the your guide an event metadatachanged has length field described as length of the track, in seconds. My test with the lastest version of Spotify android app shows that the length is milliseconds. So, is the old version of Spotify send the seconds or is it error in the guide?

Also I want to report that event playbackstatechanged is spam 2-4 times when new track is played with a little changes of position value. This is not seek change by user, it is spam by app.
