Get RSS podcast feed from SoundCloud
A SoundCloud RSS feed looks like this:
http://feeds.soundcloud.com/users/soundcloud:users:123456789/sounds.rss
You can find the UserID (here, 123456789) by examining the HTML source code of the home page for the SoundCloud user. Look for a string like this:
<link rel="alternate" href="android-app://com.soundcloud.android/soundcloud/users:123456789">
