Thank you for your detailed reply. I will refrain from further edits until we achieve consensus on this issue  I'm sorry if I made that edit prematurely. 

 I was not aware of her MySpace page  I admit that it clearly names her as "dawn Landes." However, when I look at other sources she would likely also control (her personal website http://www.dawnlandes.com/, her Facebook page https://www.facebook.com/dawnlandes, the liner notes of her most recent album, and her PledgeMusic fundraising site for forthcoming covers EP http://www.pledgemusic.com/projects/dawnlandes), not to mention virtually every third-party reference to her as an artist, I continue to believe that "Dawn Landes" is currently the appropriate way to refer to this person. 

 I think we have two conflicting perspectives here and I'm not sure either one of us will be able to convince the other  even with facts. This is because, I think, we have two conflicting narratives of the dawn/Dawn story. Mine is that a musician who started out her career clearly wishing to be called "dawn Landes" (using it on the covers and liner notes of albums early in her career) has switched to "Dawn"  I have no other credible explanation for the virtually universal references to her as "Dawn" in recent years. The lone counter-example is her MySpace page, which was likely set up with a username of "dawn Landes" when she was still lower-casing her first time (back in the days when having a MySpace page was really essential for a musician)  maybe she simply never bothered to update her username since the "dawn Landes" era? And I see no reason why a MySpace page should be seen as more reliably indicating her wishes than her Facebook page or website. Part of my perspective is that I first discovered Dawn/dawn's music with Sweetheart Rodeo, which contains consistent references to "Dawn Landes" (including cover-art that clearly uses "Dawn"), with one interesting exception: the songwriting credits say "dawn Landes" (possibly for legal reasons because it's about copyright?). Since then, the liner notes for Bluebird use "Dawn" (when not in all caps, such as the cover art). 

 On the other hand, you clearly believe that the person named "dawn Landes" has never dropped her wish to be known with a lower-case first name. I'm sure that's because you've been following her longer than me and have always known her as "dawn." To you, every example of "Dawn Landes" that I can find is clearly a case of someone who doesn't know or doesn't care about her wish to be called "dawn." 

 I'd love to find an interview with dawn/Dawn online where an interview asks her about lower-casing her first name, but I've found nothing. I easily found a half-dozen interviews by Googling "dawn Landes interview" and found that they universally called her "Dawn" and none of them asked her "What's the deal with lower-casing your first name?" Now, from my point of view, that's more evidence that dawn/Dawn really is "Dawn" at this point. On the other hand, to you that's yet more evidence of unthinking people who just don't get it about dawn's wish to lower-case her first name. Though, honestly, if it was me and I really wanted to have people lower-case my first name, I would make a point of mentioning it in the interview. Actually because the capitalized version is so omnipresent, I'd have an attitude about it! "And when are those idiots who maintain my Facebook page and website going to stop calling me "Dawn" for Pete's sake?!?! And my stupid label too? Geez..." 

 All that said, short of a clear smoking gun, I don't think we are ever going to succeed in convincing each other the proper case to use for dawn/Dawn. I suggest we submit this to a third opinion to try to resolve this. How does that sound? 

 Thank you for your support of dawn/Dawn. She's a wonderful musician who deserves to be a household name  using whichever case she prefers!
