First of all, prepare an MP3 audio file, which should be moderate in size and free from any damage. It is always 10MB, and high-definition audio is enough.

Then, copy the music we prepared to "My Documents \ Rock Star Games \ gta iv \ User Music".

Rename the file. The prepared music name cannot contain Chinese characters. So I changed it to English. Note: spaces, special symbols, Korean and Japanese can't appear either. Just rename the song and change it to English.

For example: "G.E.M.-Foam MP3"? Change it to "DZQBaoMo" MP3 "

Enter the game and select the game settings. Here we use manual scanning. When scanning, there will be a small circle rotating, and there will be a prompt that the import is complete, such as 7| 18. After the import is completed.

Then, we get on a bus by the way, and the elevator will transfer to our independent elevator. Wait a minute and see if your music has started.
