She’s not as prolific as Swift. Swift’s career is like a machine. Adele is more soul than pop. Swift is teeny-pop. Adele is moody teenager.
They are both in their mid 20’s
I do not think Swift has a good voice compared to others like Adele and Aguilera. A LOT of pop females sound the same, or they sound like they are copying Alanis Morisette.
It is interesting to research and see those who use Auto Tune and those who do not.
