Lady Gaga, Rebecca Black, Bruno Mars, or Chris Brown?

I don't like any of the singers, but Lady Gaga has the best voice, even though she sings songs that I really dislike (I'm trying to abide by your note and not leave a hate comment). I've heard her singing live and it's really impressive, but I feel like her songs are kind of repetitive and have poor lyrics. And, I'm all for being unique, but her sense of style too over the top. She wore a meat dress-and the meat wasn't even cooked! That could cause cross contamination if she were in a kitchen.
