What song should I sing?

I was thinking of singing something like "The Climb" by Miley Cyrus, "You Raise Me Up" by Josh Groban, "Because of You" by Kelly Clarkson, "Tattoo" by Jordin Sparks, "Crush" by David Archuleta, or possibly "Chasing Pavements" by Adele. It doesn't have to be one of those songs but maybe something like it or by the same artists. I = have an alto voice (I sing in a lower register). The lowest I can sing is Low D- Low C and the highest is High F (But I'm screeching so I wouldn't sing something that high.) My voice is better for ballads and musicals. I will consider any suggestions. When I win my first Grammy, I'll thank you personally, lol.
