My old URL structure was http://japanaddicts.org/mind-blowing-japanese-songs/ But almost three days back, I picked the other style that's more descriptive: http://japanaddicts.org/creativity/mind-blowing-japanese-songs/
Now I have category slugs in my post URLs. When I searched for Some Mind Blowing Japanese Songs, the third result was my website's, but with the old URL.
How do I somehow tell Google to refresh the listings of my website's posts? My website is only 24 days old, so I think it has to be pretty easy to refresh it completely? I have XML sitemaps enabled.
Please note that I am not willing to do redirects. That'll be another problem, let's keep this problem specific.
(As a further request, I would like you to open the former link and tell me whether it shows a 404 error or not, as in my case, it doesn't open anything but a blank page.)
