Any good song suggestions for performance?

Alright so talent show tryouts are in less than one week and everyone wants me to sing because they like my voice. I am a nominee for most talented girl this year, (haven't found out who won yet) and I want to show that. Uhm I'm not sure how to clify my voice...I can sing most of Taylor Swifts songs pretty well, and Carrie Underwood. But I don't necessarily want to do one of their songs..Just giving you an idea of my range. Also like Leona Lewis, Adele? Those kinds of voices. Actually idk I can sing pretty much anything, SONG IDEAS?! please. Not anything boring, nothing stereotypical, nothing dirty, etc. Thank you so much ^_^ ANY IDEAS HELP! REALLY!
