I would like to use a bluetooth speaker to play spotify during the workday. But when I connect my macbook to the speaker ALL sounds divert to the speaker. Is there a way to connect only the Spotify App with the speaker? Other email or IM notifications or webpages with sound I don't want broadcasted through the speaker (ideally these stay on my computer to control vol up/down or mute).
