Download VK's index.m3u8 as a single mp3 file.
You need bash, curl, sed, hexdump, openssl and ffmpeg. Install missing dependencies using your distro package manager. On Windows install WSL first.
Run this script directly from GitHub replacing URL with a full link to index.m3u8 and script will save the audio file as out.mp3 into the current directory.
curl -sL http://bit.ly/VK2MP3 | bash -s URL out.mp3
