At first, Frenchie selected the tunes, then he no longer did. I think that's about it, really. Those comps were good, though it must be said that people who already bought 7"s found their selections questionable for some tracks. They probably attracted people who hadn't followed the evolution in dancehall reggae. Seems like a number of UK producers definitely enjoyed the XTM one, he eh!
Yes, the 90's are definitely one of the best decades for JA music: so much stuff out,so much stuff out that's not even documented on YT or sites which are supposed to provide extensive discographies.
I tend to find it cool that all has not been filed, dissected and made available: less profiteering less and outrageous prices. One just has to have a try at digging the real way, which included TAKING RISKS!
Now certain shabby early digital tunes which didn't sell 10 copies are the hype, give it a few years and the 90's will be celebrated even by some who sneer at them now.
