Hanbyul, one of the main vocalists of the K-pop band LEDApple, has been covering 50 of today's hottest hits for his 'Music Note' project, and the results are incredible.

Music Note consists of 50 episodes where Hanbyul demonstrates his incredibly diverse vocal ability, including hit songs by Katy Perry, Justin Timberlake, Miley Cyrus, and JayZ. Check out his most recent addition to the project, a stunning cover of Lady Gaga's "Applause":

One of the best things about the project is that the profits made from the YouTube ads are donated to "Save The Children" to help them protect children's rights. For more of his incredible covers in the Music Note project, check out LEDApple's Music Note YouTube page.
