Uh, no. It entirely depends on the station. My wife has radio stations in her car that sound almost 100% prerecorded and edited together - I can never tell if someone is actually talking now or if it's just a snippet from a previous recording. However, if I listen to a very specific radio station from my home country, which I can only get via internet stream, it still feels like listening to the radio. The way of listening has nothing to do with it, it's all in the station's programming.
