Im a fan of good technical singing and Xtina just doesnt have that....YELLING, with NO CONTROL at ALL is what she does. She attempts RUNS that just go NOWHERE but leave her short of breath which i have actually witnessed myself seeing her live. This girl needs to go back and REGROUP again and consider more INDEPTH voice TRAining. I admit some R&b singers do yell when they sing however they exhibit CONTROL and are able to recover with good tone, this girl lacks that. She has talent but needs to work on it more to reach the Voice levels of Whitney, BEyonce, Aretha, etc.... It confuses me as to why she has not mastered her voice after years of being an entertainer
