In this paper we applies typical four audio watermarking technologies to protect ownership or copyright of mix music which is combined two or three pre-existing song. In experimental results, applied watermarking technologies cannot be applicable to mix music and three technologies fail to extract watermarks from mix music. This results is from mix music that does not contain full watermark information. Therefore applicable watermarking technology should development for mix music. The common problem of failed technologies cannot extract the second watermark from underlying mix music.
