imposing a capping policy where a maximum volume is imposed regardless of a user'"'"'s choice of volume selection.

14. The method of claim 1, further comprising:

lowering the volume of a first audio stream in order to temporarily increase emphasis on a second audio stream.

15. The method of claim 1, wherein the categories include at least one category drawn from the set consisting of:

music, video soundtrack, voice telephone call, telephone voice mail, e-mail notification, SMS notification, user interface sounds, ring tones, and alerts.

16. The method of claim 1, wherein:

two media requests originate from a particular application of the plurality of applications; and

the two media requests designate different categories.

17. The method of claim 1, wherein:

the media associated with the media playback requests is audio; and

determining how to route media associated with the media playback requests involves determining how to route the audio associated with the media playback requests.

18. The method of claim 1, wherein the steps of receiving and determining are performed by a set of one or more media components that are separate from the plurality of applications.

19. The method of claim 18, wherein determining how to route comprises determining, by the set of one or more media components, based on one or more policies indicated in policy data.

20. The method of claim 19, wherein determining how to route comprises changing the one or more policies by updating the policy data without modifying executable code of the set of one or more media components.

21. The method of claim 19, further comprising:

establishing a set of default policies for each category of said categories; and

storing the set of default policies in association with the policy data.

22. The method of claim 19, further comprising:

establishing a set of policies that prohibit audio routing to predetermined outputs; and

storing the set of policies in association with the policy data.

23. The method of claim 19, further comprising:

discerning the intent of an audio category in a media playback request based on the policy data.

24. The method of claim 19, further comprising:

overriding policies indicated in the policy data based on user behavior.

25. The method of claim 19, further comprising:

storing a last in wins policy in association with the policy data.

26. One or more storage media storing instructions which, when executed by one or more processors, cause:

receiving media playback requests from a plurality of applications executing on an electronic device;

wherein the media playback requests indicate categories for media associated with the media playback requests, wherein the categories that are indicated in the media playback requests do not indicate the applications from which the media playback requests were received; and

determining how to route media associated with the media playback requests based, at least in part, on the categories indicated by the media playback requests.

27. The one or more storage media of claim 26, wherein the instructions, when

executed by the one or more processors, further cause:
