Comment 12 for bug 652978

This issue cannot be solved in the sound menu. It is up to the applications to issue notification bubbles based on how the track was changed. Similarly for notify-osd: it doesn't have enough information to decide whether to show the bubble (namely, where the track-changed event was originally from).

I think apps should never show a notification in response to a manual track change, unless the track was changed using the media keys.
