First and foremost all types of swag, which is the most notable influence it had.
All types of duos coming together outta nowhere, mostly for mixtapes. Resurrecting that overfly rap with things people can't pronounce, clothes they can't fit in and cars they never drive.
Mad rappers and singers becoming super artsy outta nowhere, slang like HAM and Cray, following MBDTF it also further introduced what certain people like to refer to overproduced beats and other extremely progressive production, releasing albums digitally exclusive, incorporating very unlikely samples from unlikely genres in your music and on.
It had a lot of influence on hiphop culture, obviously not as important influence as other albums from the 90s like Illmatic, OB4CL etc, or TM101, BP, Trap Music from the 2000s. But still very big and noticeable.
