what i do to save time is add a tempo track in cubase, when the tracks not huge you can adjust it by 5bpm in a negative or positive manner, most bands dont record at like 143 timing haha
forsure man shit is tight, she has an awesome voice too, ive used autotune and melodyne but ironically the vocal editing program in Cubase 5 has been so much easier and more natural sounding too me.
