""" 
I DIDN"T USE CLASSES BC IM STUPID AND DONT KNOW HOW TO USE THEM WELL.
I used pygame to intialize the music. 
The os library to check if the files in the folder are mp3 or mp4 and to search through the file
PyQt5 to make the gui and assign the Buttons, Slider and ProgressBar
Then more pygame music methods to detect things such as get_length or get_volume. 
                                    TO USE
1. Make sure you have pygame installed (pip install pygame) and PyQt5 installed (pip install PyQt5)
2. Add Music Files (.mp3 and .mp4 and .wav files) into the Music Playlist folder.
3. Run and Enjoy.
