simfy.com | simfy.de : How to capture/download/rip/save/record songs from Simfy

Hi

I tried to download songs from simfy.de this way.
But I think they changed their streaming software.
My Live HTTP Headers shows for this song:

hxxp://www.simfy.de/#/artists/127031-Ira-Atari-Rampue/albums/323380-Space-Rocket/tracks/11891073-Space-Rocket

#request# GET https://premium.simfy.de/api/tracks/11891073.json?

11891073.json contains:

no "streaming track URL" is displayed..
how to download this now with rtmpdump 2.3?

this would be my code:

rtmpdump -r "rtmpe://c7.simfy.com:80/transit?doConnect=RN0CKCY3" -a "transit?doConnect=RN0CKCY3" -f "WIN 10,1,82,76" -W "http://www.simfy.de/flash/player.swf?1295612048" -p "http://www.simfy.de/#/artists/127031-Ira-Atari-Rampue/albums/323380-Space-Rocket" -C O:1 -C O:0 -y "mp3:N2IzNWJmOTYxNTI5NTllYWUbA4phnf7oVGoCk_ExB6NmZ rimEDqS-JRl_tXCEHihujRJuA-Zwa8K8SF3vrlxxqXmdjYyq9_0Tk_iKmBAkkbAxHls-MMwjIoYQfc_SHPjKPuKYmINLmMqK95HMVyUbGPjv9dPRrB9wLb OLr8mnGi3rFrtaofh_olQ" -o _XXtrack.flv
