I don't like this name, and I don't really care for Aretha Franklin. It sounds like another name that white people think every other black woman has, when in fact that's not the case.
Seconding the person who mentioned it sounds like 'urethra', because that's what it always reminds me of too. The urethra, for those who don't know, is the tube through which you pee. Yeah, not what you want to bring to mind when you tell people baby's name.
