What song should me and my friends sing at karaoke?

we go to karaoke every thursday night. tomorrow's theme is cowboy night..so its best to sing country music. we are used to singing songs like leave the pieces-the wreckers. kerosene - Miranda lambert. tim McGraw - Taylor swift. but this week we want to sing something different. were not bad singers but were not that great and we don't like really hard songs. can you please give us some suggestions of easy country songs for 2 or 3 16 year old girls to sing..and remember were not carrie Underwood's! lol were not horrible but we don't need to go to american idol. lol.
