Hello Rawket.
I took the liberty of editing your post so that your survey is now a one-click link, rather than a “copy, paste into toolbar” operation. I’ve also completed your survey. Being in the edu biz, I do appreciate that completed questionnaires help in your coursework. The Qs are quite well thought out, IMO, even though some of your respondents may have no interest in rock music. That’s fine though; you’re concentrating on your target market.
