Just been on a nostalgic YouTube journey through some of the stuff that was on rotation during my adolescent years. Apart from obvious, this is some of the stuff I remember watching:

Bubba Sparks - Ugly / Deliverance
Wayne Wonder - No Letting Go
Baby Bash - Suga Suga
Lumidee - Never Leave You
Truth Hurts - Addictive
Wookie - Back Up To Me / Battle
Nina Sky - Move Your Body
G-Dep - Special Delivery
Erick Sermon - React
NORE - Superthug
DJ Jazzy Jeff - Rock With You
Tha Alkaholiks - Best U Can

NOT FORGETTING: Next, Genuine, Joe, Jagged Edge, Raphael Saadiq, D'Angelo (AB'S!) Also got good memories of Missy, Luda, Redman and Busta being really unique/weird with their video's.

Eating dinner on a Saturday night watching the Base Request Show was a regular occurrence.

Not watched in years but I can imagine it's lost all it relative uniqueness now and it's just another channel...kinda like when MTV2 canned This Is Americana and 120 Minutes.
