When I hear a new song on the radio that I like, I want to know the title and artist. More often than not, the D.J. does not tell me this, and I have to try to find out this information on my own.
I used to try to rely on the radio station’s website by looking through their list of last songs played, but more often than not, that was not up to date. So I got in the habit of writing down a main lyric or two—when I was safely stopped at the next traffic light—so that when I got home, I could search online.
