A 19-year-old teen will test Australia’s laws as the first person to be charged with offensive behavior, for listening to rap music.

Nathan Michael Wilkie was charged with offensive behavior as he waited in his car listening to Australian rapper Kid Selzy, while his mother was grocery shopping.

Police heard Wilkie listening to an explicative filled song, which they deemed offensive and derogatory towards women.

The Herald Sun reports that the case will go to trial in June, where Wilkie is expected to plead not guilty to the offense.

Kid Selzy himself plans to attend the trial, after Wilkie’s mother posted a message on his page.

"Unfortunately he saw me (his mum) coming out of the local supermarket with shopping bags and left his car running and music playing to help me with my bags and the local cops pulled in, Mrs. Wilkie wrote.

Kid Selzy told The Sun the whole ordeal was a waste of tax dollars.

“From what I believe, everyone has the right to their own opinion. I have lost two of my best mates in the last couple of years in tragic circumstances and I feel that listening to his music relates to life," Kid Selzy said.

Kid Selzy’s album The Creepshow will be played during the trial, which is slated for June 11th.
