I would also highlight the recent ActionScript 3 API wrapper:

This library enables your Flash or Flex projects to communicate with SoundCloud’s API to upload tracks, create playlists, edit user info and so on. It handles all the complicated OAuth authentication in the background so you only have to deal with a few simple methods.
SoundCloud have also annouced today a Widget Javascript API.
