Here is one ugly workaround if your app can check 404 on stream:
Calling

will respond in unconditional JSON response (that is you can't get XML) with RTMP stream, that will be valid for couple of minutes or so:
{"rtmp_mp3_128_url":"rtmp://ec-rtmp-media.soundcloud.com:80/mp3:VeAGXsGTFb59.128?9527d18f1063a01f059bf10590159adb10dea0996b8c0cdb6748962c2c1b859ce6b56ee301b0b087e0695d03f6e9498fd963ef1328bc89c05e156bacca00317de55e78139e168138ead65c8fdac11f8d626674293d53f230cf5a"}
