You can use any SoundCloud API call that returns a list of tracks as a source for your widget.
Here are some good examples:
-
Lists tracks that contain "Awesome" in the meta data:
http://api.soundcloud.com/tracks?q=Awesome
-
Lists tracks that have geo tags. This makes most sense for the map widget.
http://api.soundcloud.com/tracks?tags=geo:lat=*
-
Lists favorites of the user 183 (soundcloud.com/forss).
http://api.soundcloud.com/users/183/favorites
-
Lists tracks of the group 1.
http://api.soundcloud.com/groups/1/tracks
-
Lists tracks that were created with the app 124 (SC iPhone app).
http://api.soundcloud.com/apps/124/tracks
Have a look at the SoundCloud API Documentation to dig deeper.
