Wow - I'm pretty impressed that you're so sure at such a young age Jonta .
I admire your confidence.
The absolute majority of what I write is based on "Don't make me think" (book) by Steve Krug, and "User Interface Design for Programmers" (online article) by Joel Spolsky. Or at least; I recommend these to people who design websites.
Part is from experience. I use the internet myself, and am part of a community of people knowledgeable of IT and the likes, which is often highly critical, and where my viewpoints would not be seen as extreme at all. Every so often, people are offended by the seeming lack of care I have for the threadstarter's feeling, or rough comments I give. No, I do not wrap my views in sugar, I refuse to take the time for it. No, I will not list positive things, that is for other people to do, and I do not see the point in me doing the same. Only very occasionally will I say something I like about the page.
Yes; I am working on a solution for giving feedback, where the reasons are properly explained.
I am not sure which of my points can validly be classified as a point of view. A lot of research is done on the field of usability.
You specifically quote my saying of "the few that like it, aren't worth it". I really recommend you read the SO-thread I linked to; lots of great reasons for keeping music away from websites there.
Bottom line: Its negative effects are much greater than the positive effects.
