Christina aguilera. Her vocal range is closest to Mariah Carey. By far more range than any other right now
Mariah is way better and was classically trained by her mom.
Plus Christina looks like her cords are being destroyed because of tense singing and raspy singing. Not good at all.
Ellen McLain. Only known among Portal fans. She sings amazingly.
Major Parkinson, they get decent airplay in Norway but should be huge over here.
