reven: would only be interested if the streaming was free.
i would love to listen to pandora etc in my car but mobile data is way to expensive to do that every day.
for now im using google play music and syncing to my phone, but real streaming services offer way more variety.
so if telecom/spark zero rated this data, i would switch from vodafone.
I would be truly surprised if Telecom zero-rated the Spotify data; I think the inclusion of something for no additional money that otherwise costs $13 (and it's the same product, as mentioned above) is an excellent deal in itself. To also expect Telecom to provide the data for that product free is asking a bit much, IMHO.
This doesn't take away from the mixed messages Telecom's sending as to which plans it's provided with and the various permutations therein (including possible incentives to change to a lower-cost plan. Nor does it deal with the poor data cap provided with these lower-cost plans (this is common across all carriers - many, included myself with 2 Degrees, have pointed out in other threads that we would prefer more data as opposed to additional minutes.) 500MB doesn't got far, and will get spread even more thinly if using it for Spotify. That said, given it's the Premium service, the option is always there to download over wifi and save to the device - this is how I currently operate anyway.
Personally, I'd save money by shifting from 2 Degrees and cancelling our current Spotify account (the princely sum of $3 a month!), but would lose carryover data/minutes but gain free wifi (not sure how much I'd use this, given the scarcity of them in PN). Horses for courses, I guess...
