The service, called iHeartRadio All Access, will debut in January 2017, the company said in a press release.
iHeartRadio is also launching iHeartRadio Plus, a different subscription service that offers an "enhanced radio experience." iHeartRadio has also offered the ability to listen to ad-supported radio through its app for quite some time.
The company did not mention the price on either plan, but $9.99 per month has become the industry standard for the full on-demand experience.
iHeartMedia says it's not completely ditching its radio DNA with these new plans. "iHeartRadio All Access ... will go beyond iHeartRadio Plus to include a full on demand music collection experience - but one still tied directly to radio," the company wrote.
What does that mean? One aspect: "For the first time ever, when listeners hear a new or favorite song on the radio they can instantly replay a song and even save it directly to a playlist."
As a comphrensive on-demand music library has become a commodity, streaming services have tried to compete on discovery tools. Spotify has scored big with its robot-curated playlists like Discover Weekly. iHeartMedia no doubt believes that radio, for many people, can prove a compelling discovery tool to pair with an on-demand library.
iHeartMedia isn't the only radio giant getting into the on-demand game. Pandora is readying its own complete on-demand package, and recently launched a souped-up version of its radio product for $4.99 a month.
iHeartMedia says it has over a quarter of a billion monthly listeners in the U.S.
