As a rule the public doesn't know who most artists are until the point they've got a good few big hits under their belt. I'd say Dua Lipa really only made that point around the time of Don't Start Now. Mabel is probably a couple of hits away from reaching it, so RAYE will be some distance from there.
I feel for her, and it's a horrible position to be quite literally be STUCK IN...but she's also in a much better position than 99% of other people in the (absolutely fucked) UK music industry.
I'm assuming the label aren't STUMPING UP THE CASH (despite multiple hits as features) because they are still quite un-recouped from financing her last project which bizarrely WASN'T an album (?). I imagine it's far more a case of business than emotion.
I'm amazed the label however haven't PLOPPED OUT an "GET TO KNOW Becky Hill" compilation album equivalent out for Raye to help familiarity and build an actual fanbase. Get To Know, Mabel's High Expectations and Jess Glynne's I Cry When I Laugh basically never leave the album chart as they are full of hits that people keep streaming.
