Taylor Swift is pretty. Very pretty. Very pretty in a traditional Hollywood way. And she sings very well. She is fresh, and pretty, and her music — the admittedly small amount I’ve heard of it — is full of energy.
I like her work.
Adele is beautiful. Stunningly beautiful. She is not merely pretty. She has presence. She does not look like all the other pretty singers out there. Her music is powerful.
I adore her work.
I don’t know how else to explain the difference between the two concepts.
