miley cyres is my fav she do write lot of her songs!

Tom Waits writes the majority of his own music but some he co-writes with his wife.

Marilyn Manson writes his own songs, all of them.

(Unless it's a cover but I'm sure that doesn't count)

Yes of course Shaki writes her own songs =D

Of course - otherwise I don't consider them "artists" they are performers.

Yes Katy Perry does. :)

^^

The Beatles have done a few covers but they gave each cover their own sound

nice picture of amy.

Evanescence ALWAYS write their songs together or only Amy!! thats one of the things what i love about them!and Michael writes his own songs too!Michael does everything by himself! Lyrics,Rhythm,Choreography..... <3
aww you took a pic of Amy! :D <33 love this pick!

Avril co-writes lots of her songs but then again she writes lots of her own stuff by herself too :)

that's right

Same as what emmett said. But tied with Avril is Nickelback & Chad Kroeger ALWAYS writes all of their stuff EXCEPT for one song- "Someday" with which he co-wrote with two other band mates, Mike Kroeger & Ryan Peake. But yeah, what emmett said. ^^

I don't mind if they don't, though. Songwriting and singing/performing are two different talents/abilities; everyone can't be expected to have both.

Queen does!
