Fewer choices, especially if relevant, seems nicer to the end-user.
Defaulting rules may be easier to define for user-agents as well, like pick images on flickr, pick music on play.

Also, it seems good design to enable provider or user agent to detect whether a media selected by a user matches the web intent client requirements, before actually sharing that data to the intent client.
If a web intent client only processes mp3 and a user selects an ogg file (or worse, jpeg), the web intent provider may be able to warn the user before sharing the media.

If not passed through the type parameter, which has its own semantics and constraints, that kind of information can fit in the extras dictionary.

Can you elaborate on that?
