If you want some more sample code for the SoundCloud-AS3-API, look no further: I just pushed the Scup repository to github: http://github.com/dorianroy/Scup.
Before you can play around with the code, you’ll need to install the SoundCloud-AS3-API, the Swiz framework and get an application key from SoundCloud first. See the readme file for details.
I decided to release the code under GNU license to make sure that any improvements and modifications will have to be open-source, too. Let me know if you’d like to contribute to the next release and want your modifications to be included in the next “official” release.
