Extraction of the trend genre against the usual GET tracklist

Question

I hope someone understood this, as web documents seem to be silent on this issue.

On iOS, we use the SoundCloud web API to execute various user interfaces after a user logs in. I was looking for API documents and didn’t understand how to get the list of tracks in the current "Trending" music, either for all genres or for a specific genre. For example, to get a list of tracks for a genre:

http://api.soundcloud.com/tracks.json?limit=3genres=classical&client_id=XX

So what is the url to access the tracks? It would be great to support this in our application.

Thanks in advance!
