I placed a request for an artist that I hadn't heard on a channel in the 6 weeks since I had been listening, and just recently I heard two different songs from this artist in two days. So requests appear to be working, but unless you listen 24/7, you may not catch it. Other songs I requested that were already scheduled, they responded and told me in which hour I could hear it.
So keep the requests flowing in. Actually I placed my first request before I subscribed and they asked me what hour to play it in and what channel, and just the other day I heard that song in that hour on that channel
