I just wrote a new song...?

I just wrote a new song(I haven't recorded it yet) and I need ideas on how I can get people to listen to it, give me feedback, and still remain anonymous. I want to be able to see their expressions and how they react to the song, but I don't want to show it to my family and my friends because-no matter what they say-they're only going to tell me what I want to hear. And I need somebody to be brutally honest.

Is this too much to ask?
Any ideas?

oh! I forgot to mention, I don't want to get a myspace and publish my music. I'm not exactly a big fan of myspace.

there are many sites and things you can do

like the people above, youtube
also show some people like local musicians and get responses from them, they'll give you the best responces
