If you excuse the pun, Bone Thugs-N-Harmony was easily the most melodic of the big name rap stars of the Mid-90s, which allowed the Gangsta Rap influenced group to combine that with pop sensibilities.  The result was number one albums and a rewriting of what deep Hip Hop could sound like.  This allowed this group to be a unique combination of kicking ass while thoughtfully taking names.  Their induction to the Rock and Roll Hall of Fame depends on how their always changing legacy is seen.
