The way that some of the participants of this show are able to flawlessly portray the same voice as some of your favorite singers is still quite astounding! And while there have been many honorary guests on the show, such as veteran singer Lim Jae Bum, Lee Sun Hee, and Lee Moon Sae, with the launch of season 7 of 'Hidden Singer,' here are seven guest singers that fans are dying to see appear on this show!

1. PUNCH: One of the sweetest voices in the K-Pop scene, PUNCH is known for her melodic, harmonious vocals, and she's also sung many of the most well-known OSTs to this day. It'd be interesting to see if anyone can pull off the same voice!

2. Lee Hyori: An icon in the Korean music industry and with so many hits such as "Ten Minutes," "U Go Girl," and "Chitty Chitty Bang Bang," it'd be great to see if anyone could pull off this veteran singer's vocals!

3. Jessi: Probably one of the most challenging voices to duplicate due to the huskiness, which is a staple quality within Jessi's voice; it'd be cool to see if anyone would have the skills to pull off a similar voice!

4. Outsider: We got to see many vocals on "Hidden Singer," but rarely do we get to see rappers, but why? As rapping also takes a lot of skill and ability! But imagine finding someone who sounds just like you but that can also rap as fast as you can too! Known to be one of the fastest rappers in South Korea, it'd be a super interesting appearance!

5. Hyolyn: Known for her husky yet sexy voice, Hyolyn's voice isn't as easy to pull off as one would think. Nonetheless, she has such a variety of vocal ranges too!

6. Younha: Whether it be a ballad or a pop song, Younha's powerful voice cannot be beaten! It's truly a shame that she isn't more recognized for her wonderful vocals.

7. CL: Vocals and rapping; CL has a great mixture of both, and she pulls it off flawlessly. To see if someone is able to bring on the charisma just through their voice would sure be a feat!

Many more stars are expected to appear in season 7 of "Hidden Singer," but who are some of the stars that you'd love to see on this show?
