What song should I sing for my American Idol audition?

So, I am auditioning for American Idol next month, and I am having
trouble choosing audition songs. I am a 15 year old female with a low
alto to mezzo-soprano range. Although I am young, I do not have a
child sounding voice. I have a very belty voice, yet it is very "nice"
sounding and is not harsh. Here are some options I am considering..

Listen- Beyonce
Someone Like You- Adele
Turning Tables- Adele
Happy- Leona Lewis
Jesus Take the Wheel- Carrie Underwood

I am considering the chorus's of all of these songs. I am looking for
something impressive (not "show-off") and also something fresh. In
other words..I don't want to be the 15 year old that sings music from
the 80's.
Thank you for the help!
