Why do people make a big deal about Britney Spears not writing her own songs?

Britney Fans: How come people make a big deal about Britney Spears not writing her own songs and say she's a talentless hack? Okay not all of us have the talent to write songs. She's written plenty of her songs, she's written a lot of demos for her albums: Blackout and Circus. Her record label just doesn't put them on the album cause they feel as though they wouldn't be popular.

I'll list plenty of songs that Britney has written:

Britney has written a lot of songs, her record label just doesn't just release them until there leaked by somebody on the internet.

She may not have the voice of Christina Aguilera or Mariah Carey like she used to do when she first started, but you cannot say she can't sing. At least she doesn't have a annoying whiny voice like Taylor Swift.

All of Britney Spears' songs are original. No offense to Taylor Swift but all of your songs sound the same.

Anybody agree? Also not all of us can play instruments. Some of us just may have the talent to sing or to write songs.

2008: Circus Album:
