Here’s a quick start for any radio newcomer, as well as a reminder to broadcast veterans:
Use what’s unique to you.
For example, I’m a musician, having played guitar since I was eleven years old. And it was about that age that my mom taught me to sing harmony.
That led to doing literally hundreds of parody songs in my on-air career. And that was way before we had the technology to just take out the vocal and insert a new one. Or, God forbid, using A. I. to “write” and produce a song for you. I had to recreate the song one step at a time.
And thanks to reading MAD magazine since I was about seven years old, I had a decent sense of what would make a parody song funny. (Those people were geniuses.)
Use what you have that most other people don’t have, and you’ll stand out.
