For some reason, perhaps because I obsess about music more than most adults in their mid-30's do, I haven't been able to get Christina Aguilera's performance of James Brown's "It's A Man's World" out of my head. I'm a Christina fan; I liked parts of her most recent album very much, and I thought "Ain't No Other Man" was one of the best singles of last year. But having watched the performance again on YouTube I've come to the opinion that her performance was empty vocalizing and symptomatic of the problem of so many talented singers today - they confuse oversinging with having actual soul. Christina sang over those lyrics like a Mack truck running someone over at 75mph - a lack of subtlety combined with a series of empty vocal gestures. She's got the pipes - but to me it felt like she could have been singing any lyric, and that she gave more thought to how she was going to impress everyone in the audience as opposed to how she was going to communicate with them. It wasn't James Brown's influence I felt up there - it was Mariah Carey's, and for me, that says it all.
