Song I can sing for?

hey everyonem, from past questions a lot of people lol know that im a youtube user i sing on youtube and I had a fight with a friend last year and he said i could never be a good singer but today i was offered to sing at something professional in my town.(big town lol). and so, I wanted to post a vid on youtube to show him what I have become, even though he said I could never do anything....but i cant think of any songs...any good ideas for a good song for that? (no this is not revenge but he told me before I walked away, when i become something to put a youtube video up to show how 'good" (he used sarcasm on that lol) i am. So yea...lol help please? And i love country music so thats why i put it here lol.

um...i really dont think OUR SONG is a good song to sing to show someone you have become something. (and besides, I already did that song and leave the pieces on youtube last week)

I love Carrie Underwood, so naturally...Carrie Underwood!

If you go to youtube.com and you type Carrie Underwood Carnival Ride (that's her 2nd CD) or Carrie Underwood Some Hearts (that's her 1st!)

I really like Carrie Underwood's So Small. It's about these 3 people who have problems at home, and this teenager goes in front of a car, and that guy slams into a woman, and all 3 have a flashback about their problems and they're gonna die and all, and probably wish they had more time, and time goes backwards, and all three go home, happy....and forgiven.

umm.. if u wanna sing a country song Our Song by Taylor Swift sounds kinda countryish and or u could sing Bubbly by Colbie Caillat or maB Unwritten by Natasha Beddingfield.. i dunno sing whatever doesnt mattr

Independence Day or Wild Angels by Martina McBride
X's and O's by Trisha Yearwood

our song by taylor swift

Not Ready to Make Nice by the Dixie Chicks, and then throw the finger at the end!

"How Do You Like Me Now" by Toby Keith...lol

i think u should no one by Alicia Keys
it would send a message to the boy/person and tell him that no one can mess with u.
or sing never under estimate a girl by Vannessa Hudgens
it also sends a message and he would get the point.

wasted from carrie underwood
teardrops on my guitar from taylos swift :)

how about Carrie Underwood-So Small

red high heels by Kellie Pickler, picture to burn Taylor swift , who said by Hannah Montana not country but yeah that's one that's not indicating you liked him like the other 2 do unless you did . Fool hearted man by Jo Dee Melissa .A place in this world by Taylor Swift, if not 'm sure you'll find something. (I love her) I hope I helped and keep singing! ,
