Internet “radio” is whole nother kettle of fish though, and will continue to be so until unmetered cellular data plans become ubiquitous. Terrestrial radio is still dominated by what you can pick up for free OTA on your commute.
(However I will take this opportunity to plug soma.fm’s multifarious channels, as well as KALX, WFMU, Pirate Cat, and Radio Valencia, all of which are freeform and eclectic so you don’t know exactly what you’re gonna hear depending on who’s DJing at the moment. Probably not any smooth jazz though.)
