Let's first talk choice of material which we refer to often. You certainly want a song that speaks to you. But such a classic song from a monumental musical like Dreamgirls belongs firmly in the hands of someone who can compete with Misses Holliday or Hudson.
Second - can we talk about arrangements? Whoever is helping edit her karaoke cuts seems to be snipping with a pair of pruning sheers to the point that the lyrics phrases make absolutely no logical sense at all. The composers would be cringing.
And then the singing. So much for modulation. She is singing in all keys and all at the same time. And I'm not even going to mention the costumes or the bad gesturing. This Dreamgirl is a Nightmare.
