If you've listened to any mainstream rap in the last decade, you'd definitely hear the influence. If you're automatically saying it would be a hard pass though, I take it you don't (and that's perfectly fine). Around the late 2000's - early 2010's, there was a huge shift in the direction of rap. Lex Luger, who produced majority of Flockaveli, created a new orchestral sound for the trap subgenre (beats like BMF, Hard in da Paint, HAM) which brought the genre to the mainstream, and a lot of other producers started trying to replicate the sound. The entire 808 Mafia production crew ended up growing from originally Lex and Southside to TM88, Fuse, Tarentino amongst many others and rappers from Gucci, Rick Ross, 2 Chainz, Meek Mill, Future, Young Thug, and Travis Scott frequently featured these producers on their tapes. Artists like Chief Keef have also molded their sound around the style that Waka popularized. The entire south started to really blow up and a lot of the production style as well as the "loud, in-your-face delivery" you hear on Flockaveli can still be heard in today's mainstream releases.
It's not for everybody & you don't have to enjoy the influence it has had, but it definitely is an important release in my opinion.
