A radio stinger is something that you could use to split up one section of content and get to another. A radio station may get from an interview to a song using a stinger. A podcaster may get from talking to someone into the show outro using a 'stinger' or 'sounder'. Shotguns are similar to stingers in that they are short but instead of spoken jingles shotguns tend to be sung jingles. They are usually used by music radio stations to get out of ad breaks and into music. In some countries (such as the USA) stingers are legal requirements to identify the radio station every hour.
