To celebrate Hip - Hop's 50th anniversary, Billboard has crowned the top 50 Greatest Rap Group of All Time.
The entire list features some of the biggest names from the Hip-Hop world, but there can only be one number one.
Here's Billboard's top 10 rap groups of all time :
2. Wu-Tang Clan
4. A Tribe Called Quest
5. Run - D.M.C.
6. Public Enemy
7. Eric B & Rakim
9. De La Soul
10. The Roots
This rank was determined by taking these criterias in account: body of work or achievements, the group's cultural impact and influence, the group's longevity, and their lyrics and flow.
"Inclusion on this list is based on the accomplishments of the group as a unit — not what the individuals may have separately accomplished," Billboard editorial team wrote.
"It took much deliberation and even deeper discussions to reason our way to what we believe is a well-thought-out, authentic list that reflects hip-hop’s foundational pioneers, evolutionary trailblazers and contemporary disruptors ."
