There's also the option of downloading programs for offline listening. This can be done with the radio - as well as through smart speakers, cars, and other internet-connected devices.

It's not uncommon for online radio to offer a wide variety of stations - and a wide variety of genres. However, there are also limits to the number of stations that you can hear at any one time. In addition, the quality of your stream will determine how much data you'll use. You can also listen to your favorite radio station on your smart phone. If you don't want to use your mobile data allowance, you can also connect to a public wi-fi network. The downside to this is that the quality of the audio may be diminished.

The good news is that there are a few apps out there that will help you listen to your favorite radio station without your cell phone data allowance eating up your telecommunications budget. Some of these include Audials, Radioplayer, and BlogTalk. The latter two also offer built-in audiences, allowing you to get your radio show into people's hands - literally.
