You are right.
But a registered user could also be a 'leecher', downloading sounds with an auto-download robot and therefore slowing down the experience for other users.
I will change it so it appears less often.
However, keep in mind that you can refresh the image is too hard to read.
Cheers.
Sorry, but that captcha thing is a pain in the ass. Why does a logged in user always has to confirm that he is not a robot? This is barely necessary, isn't it?
