In reply to I hate b&w b itchezz . They both not sht.

Well this is easy to answer...

You give a song to a more established artist with not only a bigger fanbase than you but with the machine of a major label behind it you will get some kind of cheque. You take a risk of a really good song being released by you an unknown independent artist, then there are no cheques unless you blow up or someone popular covers it afterwards.

Teedra Moses's Complex Simplicity is one of my all time favourite albums from start to finish, but would never reach the highest of an already established Christina who was selling an image that beast really Teedra's, but a song that was, and established her as a song writer as you could hear her style with other artists that she wrote for.
It's the same as the Missy situation, Missy has often said that she doesn't feel that she is a good enough singer to sing all of these classic hits that other artists have sung of hers, you write the song, produce, give to an artist who can do the job and an business that will promote it and make money.
Sound sensible to me.
