-----------------------How to use-----------------------
1. Go into the tracks page of the user you want to download the tracks from
2. Click on "Load tracks" to load all available tracks of the user (the script is scrolling down automatically to do that)
3. Click on Download and wait until it completes
4. A modal will pop-up and allow you to copy the track names and the URLs (in a 2 line per track txt format)
5, Copy it into your downloader of choice or into the provided Python script
