Juli Clover, writing for MacRumors:

As part of the winding down of its iAd platform, Apple today sent out a notice to customers who listen to its radio service letting them know the radio feature is being discontinued at the end of January.

In the email, Apple says that Beats 1 radio will be the only free listening option available to those who do not subscribe to the Apple Music service. Customers who listen to radio stations sans ads with an iTunes Match subscription are also receiving the emails and will no longer be able to listen to radio stations as an iTunes Match perk.

Bummer.
