lol? X tried to hit an E5 last year and cracked horribly. That's a note Kelly can hit in her sleep. X couldn't sing any of Kelly's recent singles except maybe Don't Rush. X is very, very touchable, considering Kelly could easily do a number of songs that she can't nowadays.
Educate ha
Christina s**** a brick trying to push out those weak D5s on MLJ while Kelly just opens ha mouth and slays an F#5
Yes, not shrieking when you hit those notes and rubbing your vocal cords together to produce a sound that you can't otherwise. Kelly's belts are achieved with proper mixing and thus she has a much wider belting range, whereas Christina shouts her notes and just prays to hit a high one.
