Examples of proper nouns that are singers:
* Beyoncé
* Elvis Presley
* Taylor Swift
* Adele
Here's why "singer" isn't a proper noun:
* It's a common noun: It describes a general category of people who sing.
* It's not a specific name: You can't point to a specific person and say "That's the Singer."
