Private Radio is catchy, and that is a reason I like it. I also like that it is about insomnia without her ever having to really talk about sleeping or having insomnia. When I think of insomnia, I think of many thoughts being in my mind, and I think Vanessa gets that across in the song with looping vocals over vocals. Your mind is going, you can't sleep, and in the song, there are all these vocals, and they are fast, and they loop. At the end, there are like 3 or 4 vocals loops over each other. It is like insomnia of the mind actually put to music. Maybe I look too much into it. But I think that is why the song is brilliant.
