the reason why you were listening to "Celine Dion, Westlife, LL Cool J, R Kelly, Usher, Lucky Dube, Kevin Little and so Many others" is solely because they were producing better music. period.
nigeria is doing well for herself in africa(truthfully sub-sahara africa) is because it is now beginning to follow the footsteps of the western world.
when you compare nigerian hip-hop and blues to that of Celine Dion, Westlife, LL Cool J, R Kelly, Usher, Lucky Dube, Kevin Little and so Many others during that time it is beyond obvious that nigerian music was waste material.

thank goodness, the likes of don jazzy, dbanj,wizkid, olamide, etc are putting nigeria on the map. As far as music goes, nigeria has a long way to go.
