if i was a singer, i wouldn't say randomly "i couldn't name 5 Whitney Houston songs, but i'm getting money so that's all that matters." that's just tacky.
And also, are you a rapper or singer? if not, then who cares if you know 5 songs. But take myself, I work in a very specific field of research, so if someone asked me to name 5 ppl in that field, I can because it's my job to stay up on past events and how they shape future innovations. and to me, that's kind of important. biggie wasn't just a fly by night rapper, but Lil Boat probably will be. And when it comes to skills, sales, fandom, I'd think an up and coming rapper would study the greats (even if they don't like them) to learn how or how not be successful.I mean, I don't fault him...but personally it does make me think an artist like this is only for money. and if that's true, that's perfectly fine.
