Here's a lil Python 3 script I made that takes an URL from an album uploaded at KHInsider.com and downloads all the music for you without needing to make an account!
Python 3.6 and up required, as well as a couple dependencies. I'd appreciate some help to make it a bit better, feel free to send a PR! I wanna add a way to output the content to an specified directory rather than to the main one, add a progress bar if possible, or general speed optimizations (I'm not that experienced with async python).
