First: choose a song at will-right click-music tool-copy the song to the Walkman, then you can choose the song you want to copy, and you can get the song and LRC lyrics file.
Second: Open the cool dog, and there is "My Application" in the rightmost column. See if there is an option to "copy MP3". If not, click "Add App" at the bottom, then find "Copy MP3" on the left and select "I want to add". After success, the option of "Copy MP3" will appear on the right. Click to enter.
Special note: 1 When you compose music again, these songs should be in your cool dog music playlist. You should play them to ensure that the lyrics are normal (in fact, you just need to click the lyrics in the cool dog when you play songs, because sometimes you can't copy them without this song in your cache lyrics folder). 2 When composing music again, you can't select songs in the File Directory.
I'm exhausted. If you are good, give me some encouragement.
