The reason why FM receivers are present on smartphones is that they can be used to locate your position by noting a simple thing as signal strength of transmitters. More advanced methods makes use of SNR, frequency deviation and multipath interference characteristics. And the same method can be used for WiFi which of course makes collection of such data very useful for localization purposes where GPS etc isn't useful. Arrival time of a radio signal that is reported to the operator from many devices may also be used for the same purpose.

I can very easily say that statement is false. At my office we have a XM Radio running all day, go into a restaurant, Either a local TV or Radio station is on. my car radio has the nearest top 40 station currently set. for me, listening to the radio is fairly mindless background filler, but I like it because it keeps me from hearing compressors and cooling fans and road noise and whatever.
I guess you could call me techno-challenged, because i refuse to pay for a cellular data plan when I’m already paying $80/month for 6M/s at home. (Live in the sticks and the cost of internet goes up) so that rules out Pandora while driving (never mind theres a 40 mile dead-zone around my town, service is damn good in town though, we just got 3G)
Just remember, what is true in a hundred-thousand person city isn't necessarily true for the rest of the country/world
