1. Lack of promotion 2. Their music doesn't appeal to a lot of people just like "mumble rap" doesn't appeal to a lot of people. 3.there album maybe isn't that good 4.if rapper goes mainstream he'll be overrated aka more successful and people who swear they love him will turn on him and say he sold out he's not good anymore look at chance don't ask how come or why a rapper is underrated when there are a lot of reasons it's not "oh he doesn't mumble" or "oh he has no face tats) FYI face tats isn't new) or he's not doing drugs yeah cause every underground was never smoking weed back in the 90s if you don't want a rapper to be slept on or underrated just support them cause bashing the mainstream rap that underground rappers and fans care so much about isn't going to help there are more talented artist out there people too lazy to look up because if the mainstream media y'all hate so much is not feeding it to you it doesn't exist. That's why you go people saying "hip hop is dead" or "rap is dying" ect every year we all know those people are not about the culture they're "rap trolls" who only speak bad on hip hop because they want to see it completely gone they don't care about the underdogs they just look down on them because they just was spread hate they're like the "Trump supporters if rap"
