R$3$: Investigate and implement a new feature inspired by a real DJ program.

$$ To complete this requirement, you need to research DJ applications and identify a feature

to implement. You do not need to run the other DJ applications $-$ you can use YouTube

and other resources to find out what features other DJ applications have.

$$ Implement a DJ$-$related feature that you have seen in another DJ program.

$$ In your report you should present a screenshot and analysis of another DJ application and

the feature you want to implement. Then you should explain how you have engineered

this feature, talking about the classes and other OOP constructs you used to do the work.
