The long and short of accessing Optus' Music Streaming:

+ you must be on their specific 12 month SIM Only Plan (although you can still buy a phone)
+ you must register and activate the Music Streaming from your Optus MyAccount
+ you must access the music through the apps listed in the Optus MyAccount, and not other websites (similiar to accessing Free Apps through Freeway).
+only the actual music streaming is free: all adds, banners, analytics etc consume data
