Music Freedom on Magenta 55+

I just switched my account from a Prepaid plan which is no longer offered.  On that prepaid account I had the ability to stream unlimited music at no additional charges.  I have scoured this web site looking to see if my new postpaid plan, Magenta 55+, has this feature.  I am supposed to have 100GB of high-speed data but it gets throttled back if I use greater than 50GB.  Does having unlimited data replace having Music Freedom?
