Some other details I’d like to mention (that some of you may find interesting).
1. I’m under the impression that 103.7 might be one of the most listened to radio stations in the city. I think I was a bit off with my previous assessment; actually, it seems more like an AC format as opposed to classic hits. Regardless, there appears to be a male and female host paired up throughout the day. If you listen long enough, you’ll hear some English songs thrown in as well (though some seem atypical for AC). I heard “Stitches” by Shawn Mendes (typical of AC), and then “Adore You” by Miley Cyrus later in the day. I don’t think any AC radio stations in North America gave that song any airplay, even when it was new. Regardless, this station seems to be very popular among middle aged adults, and you’re likely to hear it around town.
2. There seems to be a rule that all radio stations must time out exactly at the end of the hour. Each radio station airs a series of “beeps” around the 59:55 mark of each hour, with some sort of station identification airing precisely at the top of the hour. It seems like some of the hosts try to stall for time so they can time the hour just right.
There don’t appear to be any formal legal IDs. I listened to Hit-Fm for a decent amount of time while driving around over the past few days. The legal ID is just an identifier stating that you’re listening to Shanghai’s #1 radio station for hit music (as I mentioned before, all liners are in English).
3. I believe there is also Chinese CHR on 107.7 as well. This station appears to be similar to 101.7, but I don’t think English songs are ever featured (whereas you may hear an English song once in a while on 101.7).
