Wasn't paying attention to this in time to submit but here are mine based on the unscientific criteria of "listened mostly/only to this artist for an extended period of time.
1) The Clash
2) Tupac Shakur.
3) Def Leppard (was young and rocked a Joe Elliot mullet as well.)
4) Rage Against the Machine.
5) Oasis
6) Rancid.
7) The Damned (saw them in 80s, 90s, and even 2019 in NYC).
8) Run DMC.
9) Metallica.
10) Notorious B.I.G. (this selection conflicts with #2 on this list.)
11) Rocket From the Crypt
12) Dropkick Murphys.
13) N.W.A. who I actually had a chance to see live in late 1989 with the entire original lineup and PASSED IT UP.
14) Smashing Pumpkins (saw them AND PEARL JAM as completely unknown opening acts for Red Hot Chili Peppers in 1991 I think.
15) Nirvana ( also saw when largely unknown.)
Seems like hip-hop fans are in short supply on this forum so that's me representing then!
