that's why I'm okay with the fact about youtube links as you also already explained the basic introduction. It's just that nico nico douga tends to load very slow or doesn't even buffer in comparison with youtube or it has anything to do that I don't pay for premium account, so nicosound is the better alternative but without comments and video.

Thanks for the link! Somehow even with google, I didn't find that community and somehow I missed it if someone has mentioned about it.
