context 3 means Music
The user is listening to audio, such as music or internet radio.
When to send it
Send 3 when the content is something the user listens to: a music stream, internet radio, or another audio service. Podcasts have no value of their own, and 3 is the closest fit for them.
Buyers use 3 for audio targeting and to avoid sending visual-only creative. It is confused with 1 when a music video plays, which is video content, and with 4 for music apps whose screens the user is browsing rather than listening to. Pair it with Audio.feed to say what kind of audio service it is.
