It happens that the video as a whole is not necessary, but the music from it catches so much that you want to listen to it separately. It happens to me a lot, especially if the melody is stuck in my head. I was looking for a convenient way that would allow me to quickly select only sound. In the end, I decided that using Snaptik is the easiest way to do this: just a couple of clicks, and I already have a ready-made file that can be listened to in any player.
