Adverts disappear when you get an account and sign in. Especially if you block them. Slow? On a mobile perhaps. But on a decent computer with a decent Internet connection, it's fine. Broken links? No idea what you're talking about unless you mean missing videos. At least there is a proper system for putting videos on the site, and it is no more prone to the whims of YouTube video removal than this site is.
I'll get the chip off the shoulder when some people on here stop it with the ridiculous snobbery towards that site, and the strange idea that some seem to have that it only deals in commercial music and chart fodder, and that Roll Da Beats is some kind of exclusive haven for elitists and those 'in the know' when the reality is the majority of the information on here is on there as well, and was often 'on there' first. I get it's a bit 'mainstream' and everything, what with the adverts and what have you, but if that's what's required to keep it running, so be it. And like I said, if you don't like the adverts, block them.
Plenty here too, some of which I've corrected. The reality is, for all Who Sampled's faults (and you know I know there are many) it's still the best resource of its type, and as long as it is the only one on which you have the videos on the site with timestamped references, plus the ability to view connections / sample chains easily it will remain so. But I guess the fact I think that's a better system than scrolling through comments on a forum, a clunky search function, a fraction of the aforementioned site's content and a core user base of about five people puts me in a minority. This site is a decent resource (obviously it's more than just sample info) and has its uses, otherwise I wouldn't be here. But don't pretend it's somehow superior to Who Sampled, because it isn't.
