Its called Lieder.
a song i know is mist
Well, I'm not sure of your music likes but here are some I can think of off the top of my head. Halo by Beyonce. In My Head by Richy Nix. My Immortal by Evanescence. Need You Now by Lady Antebellum....
I myself am a piano player and would suggest Fur Elise. It is quite easy, but still a good song.
