If you just need to use the music box to practice singing, that's easy. Because it’s hard to find accompaniments to download, but Kuwo Karaoke from Kuwo Music Box is a very good tool. Find the song you want to practice, open it, and then display the lyrics interface. There are several transparent small navigation "Lyrics", "MV", "K Song" and "Error Correction" on the upper left side of the lyrics. Just click on the karaoke song. You can practice it with the original sound or with accompaniment singers. If you don’t understand, you can ask me and I will continue to help you answer~~
