Sprint today as part of its announcement of the exclusive Harman/Kardon edition of the HTC One M8 also announced a new deal for Spotify subscriptions. And it's extended to iPhone owners as well.
All new and existing postpaid (ie not pre-paid) Sprint customers will get six free months of Spotify Premium, if you're on a "Framily" plan. In addition on working with iPhone users, those on Android and Windows Phone can also take advantage of this deal.
And after the initial six months, you'll get a discount on your Spotify subscription, which varies depending on your level of Framliness.
Here's the deal.
