Adele's voice isn't supposed to be about 10 second vocal runs or trying to hit the highest notes (which most people find annoying after awhile). Adele didn't study Whitney or Mariah's voice, she studied artists like Etta James, Ella Fitzgerald, etc, which is a completely different style of singing (and typically more preferred).
Her voice is actually harder to imitate then voices like Whitney, Mariah, etc because it relies on tone and emotional quality and those aren't things you can just imitate. It's not that difficult to train your voice to do vocal runs. That's why when people cover Adele songs, they sound good technically but completely lack the things that makes her voice so good and unique.
In my opinion, Adele does have one of the best voices and the public definitely thinks of her as one of the best voices out right now.
OMG. Yes. They are playing SFTTR at ''Radio Transamérica'' right now. It's one of the biggest pop radio stations of my country. Love to hear this song on SKY TV.
I'm okay with Adele releasing in the summer. I don't think her sales would be bad if she released in the summer.
I guess it depends on the new single...Releasing one of her typical power ballad in the summer wouldn't be the greatest idea.
But I trust her.That bitch knows what she's doing.
make that 2049
