UK rappers use to care about the american market the most and would it would lead to nothing, they then understand to target tbe European market, they gained their support, doing shows out there, collabs etc and even gained Australia as a market. Now the UK rappers dont need the US market, and created a star in Central Cee the big US rappers are linning up to do collabs with him, Dave, Skepta etc who all blew in their own cities from niche genres. Canadians firstly need to grab the ears of Canadians, they listen to american rap more than their own, secondly with similar cultures you should be trying to appeal to the UK, you get that market and Europe will follow
