Ask for the background music in the TV series "Light and Shadow", the female voice humming, the title of the song or directly share the file with me.
Well, I have a method, but it's a little more complicated. You can intercept several connected small videos in Youku Video (which is now copyrighted by Youku), then combine them into a whole, and then use the software store to download the "Video Background Music Recognition" software to identify pure music and save it.
