1. Lady GaGa

Lady GaGa is a total weirdo, but that's what makes her so interesting to watch. She also has an incredible vocal range. She isn't just a great singer, she is an amazing performer too.

2. Ariana Grande

Perhaps what is most impressive about Ariana Grande is her ability to slay when she's only 22. She can dance and sing, and her riffing sets her apart from your average musician.

3. Demi Lovato

OK, so I know we all think of Demi Lovato as that awkward girl from Camp Rock, but her live performances prove that she should be taken seriously as a musician.

4. Adele

Hello, it's me. A perfect human serenading you to sleep. Adele, is your talent even real? How can someone sound this good live? See for yourself.

5. Beyonce

Beyoncé, is your hair ever NOT blowing when you perform? You are perfect. I think everyone in the world has a crush on Beyoncé because she is the definition of a goddess.

6. Ed Sheeran

Ed Sheeran is dripping in talent. During his concerts, he uses a "loop station," which gives the ability to have a one-man-show. Very impressive. His lyrics are also super romantic, and even if he's not that cute (sorry, Ed), he will still win your heart over.

7. John Mayer

John Mayer may not be a very nice guy, but his voice is smooth and his guitar skills are on point. He may not be touring anymore, but watching this video will bring you back to the early 2000s when his career was still fresh (and no one knew how much of a jerk he is to the girls he dates).

8. Justin Timberlake

Although Justin Timberlake isn't doing much with music anymore, we should never forget why he is famous in the first place. Note the female back-up singers.

9. Justin Bieber

I never wanted to be a Belieber, I can't help it. Justin is so good live, and he has been since he was first discovered on YouTube (watch video below to watch mini JBiebs slay "With You" by Chris Brown).

He is SO CUTE. You may be torn about who to believe with the whole Justin and Selena drama, but you can't deny that this boy has pipes (even though he used to sound like a woman).

10. Maroon 5

This song will really bring you back to your childhood and remind you when you first fell in love with Adam Levine.

11. Sam Smith

Sam Smith has one of the smoothest voices I have ever heard, and he makes it look so easy. He sounds better live than he does in recordings. Are you even real?

12. Ella Henderson

Ella Henderson may have only come in sixth place on the X Factor in 2012, but she will always be number one in my book.
