The simplest answer is Yes. Most karaoke machines allow you to play MP3 along with MP3+G. Karaoke machines have adapted well to changing technology and have transformed into a more versatile version of themselves. Hence, most karaoke machines support various formats. I would say almost all karaoke machines support MP3 but it's still a good idea to check with the manufacturer before making a purchase. For those who are wondering what MP3+G is, let me elaborate. MP3+G is an enhanced version of MP3 and supports graphics along with the audio. These graphics or visuals are great for reading lyrics. It is quite similar to CD+G. Any of the latest karaoke machines should support MP3+G.
