Q: i've been trying to find a n y song in those keys and at this point i'm convinced they don't exist (or i've overlooked some idk).
A: off the top of my head, first i think of "thrift shop", that macklemore hit which was in G# min. Also i believe ed sheeran had a big hit within the last few years in G# min. what was it called ..... oh that's right "sing." there was a big dance hit within the past decade called "sweet sweet nothing" which i think was in G#min or you could consider it B depending on how you orient it.  there was a huge instrumental techno/dance hit from the 90s i think, "do you think you're better off alone", which i believe is G#min. I'm a survivor by destiny's child was in G#min. speaking of 2000ish 'bye bye bye' is G#min. "Timber" by kesha/pitbull was G#min. there are many more that's just what i can think of off the top of my head. oh yeah "tina turner" what's love got to do with it, that's G#min. also "family affair" mary j. blige is G#min. As for Eb min (D# min) let's see, there was one a few years ago called i "won't black out" i forget who it's by... just looked it up that's by breathe carolina. was a big hit around 2009. That rihanna one with chains/whips ..... s&m? that's Eb min for sure. speaking of which, rude boy was also Eb min (also rihanna.) A very popular ballad from around 2002 "my whole life has changed..." by ginuwine? that was in Ebmin. Stevie wonder "i wish" and "superstition" are hugely popular standards, both in Ebmin although many bands play them in E to make it easier for guitars and harder for the singer. Low by flo rida was Eb min. Ain't Nobody by chaka kahn is Ebmin. there are many many more but i'm trying to just stick to the popular ones because that's what you mentioned
