You still have to keep in mind that these are their picks, the music they like to listen to and take inspiration from so they're bound to have familiar ideas people could speculate on. BoC are just as impressionable as anyone, they are not beyond influence themselves.
Until BoC come right out and say "yes, that is us" I would rather appreciate the music I like from that mix as artists I don't know and give unknown entities the kudos they deserve instead of stealing it from them and attributing it to BoC.
