As a celebrity it seems like Beyonce is the bigger star

but as a musician it seems like Britney is the bigger star

Since "Music" is their main profession

which "title" is better to be view as

Bigger Celebrity? Or Bigger Musician?

Uhm Beyonce has been outselling Britney since she went solo...

It's the opposite. Dude Beyonce is way more talented musically than Britney, while tabloids care more about Britney's personal life. You're delusional if you think Britney is in anyway a musician. She mimes, cannot dance, and does not write her own music. She's a glorified drag act. Do I stan for the bitch? Yes, she's amazing, she pulls off her drag act very well. Do I stan for Beyonce.. no, to me her music sucks, but she's a lot more talented. So yes, although I love Britney and she's my 5th most listened to artist on my Last.FM, it's simple, she sucks at music but is the bigger celebrity. Is she more successful than Beyonce musically? YES.
