I have tried it before and tried it again today. I don’t accept it. I registered, logged in, and collected it again. Finally, a failure message popped up. Maybe there just weren’t enough crystals. hehe. I had no choice but to copy the dance music to Baidu and find a similar website called DJ Music. After several clicks---MP3 high-quality download came out and it was successful. If you have a special liking for crystals, it seems that you can only copy the dance music on Baidu and find a website where you can download it. I tried using the browser's method of searching for files, but it didn't work either. I have used all the tricks I used for recording back then. hehe. Happy New Year! All the best! Sorry, I couldn't give you a solid answer.

I have used this method to download three songs on Baby DJ. It seems that the arrangement of Crystal's dance music suits my taste better. Copying all the song titles won't work, because the song titles on the two websites are slightly different, so you can only choose the key pattern. hehe.
