I get what you're saying but I don't feel like there are a lot of websites to discover music.
Besides hypem, pitchfork and sixtyone do you anymore? And I think they could greatly be improved. Music Discovery is a new thing, before we just had the radio, and it's still not as good as it could be.
I pay for and use MOG and their recommendations are pretty good. Certainly this could be the case that "everything sucks I am going to execute better than everyone" but it's a sexy problem (not a schlep) and everyone seems to be working on it.
