Fun fact, there is some radio streaming built into the iPhone (all the Siri stuff too, so HomePods).

I found this out when a DJ on the radio kept yelling “hey siri play… <insert call sign here>”, and the same with OK Google.

I was getting annoyed, because he kept triggering my HomePod, but it didn’t understand what he said as the command. Then one time it worked. The DJ yelled and my HomePod kicked on and started playing the same station.

I assume this harkens back to the Internet radio that iTunes has supported forever.
