Can you put any CD in a karaoke machine?

Not all CDs can be used in a karaoke machine. Karaoke machines require specifically formatted CDs known as karaoke discs or karaoke CDs. These discs contain the music with the vocals removed, allowing a user to sing along. Regular music CDs do not include this separate audio track with the lyrics removed, so they cannot be used in a karaoke machine. Some advanced karaoke machines may support additional disc formats like DVD or USB flash drives that contain karaoke content. Always refer to the karaoke machine's specific user manual for compatible disc types.
