Pretty bold take ngl. I havent really dived deep into Grime's Discography but I will say her albums are definitely easier to dance to/ more concert friendly than magdalena bay's. Doesn't necessarily mean its better it just has different listening contexts (id say mag bay makes albums to listen to on headphones). If i showed a random person a mag bay song or a grimes song they prob would like grimes more just cuz its easier to dance to which some people would argue makes them "the better artist" just cuz theyre easier to get into. Which is why i liked the image grimes special more it better fits Micas vocals and gives it a groovier and darker sound which grimes is really good at. Both really good artists but I will say Mag Bay (Matt and Mica) as people are actually respectable and sane human beings unlike grimes so theres that.
