Songs I can sing on youtube?

I ran out of songs to sing on youtube lol...what are some good songs(any kind of music besides rap and metal) that I can sing on youtube? An example of me singing on youtube is here:(this song was on acapella but I usually sing with music in the background.)http://youtube.com/watch?v=WpkZQ6r48xc

I turn to you by christina aguilera

glycerine by bush

you should sing, no one by Alicia Keys, or Hannah montana, We got the party with us, or Taylor swift, Tears on my guitar

why do you want to sing on youtube anyway?? i dont think anyone really watches those, do they? It would be more worthwhile to sing a song in public.
