As you may (or may not) know, we do not currently have a dedicated API support team. Our customer support team is focused on providing account-related support and we do not have the necessary skills to handle enquiries about how to develop your application.
That being said; I would recommend looking through SoundCloud’s Stack Overflow page (http://stackoverflow.com/tags/soundcloud), and reviewing our developer website (https://developers.soundcloud.com/). These are the support resources we have in place for app developers.
Although we cannot provide support regarding the actual coding aspects of your application ourselves, we would really like to encourage everyone to ask their questions and start some conversations here, as chances are someone might have already experienced the issue you are having, and might be able to provide a solution.
Thanks for understanding.
