I am a newbie still to reggae music but I have grown fond of it. I have various favorite artists that do music under this genre:

--Elephant Man (I heard about him when I heard the "Switch [Reggae Remix]" by Will SMith feat. Elephant Man from the album Lost & Found
--Shaggy
--Mr. Vegas
--Sean Paul

There are more artists I'm gonna listen to like T.O.K., Red Rat, Kardinal Offishal, Wayne Marshall and more artists out there. Maybe some reggae songs that is wieldly popular is by Sean Paul, since most of his songs are top hits. Like "Temperature", which Sean Paul used the Apppluase Riddim. And "We Be Burnin'" with the Stepz riddim. I'm still learning riddims but I have a few favorites, from named from albums like "Riddim Driven" and Greensleeves albums.

--Stepz
--Gangsta Rock
--Sexy Lady Explosion (I enjyed the riddim because on the album from Riddim Driven, it has "Hey Sexy Lady" by Shaggy/Brian & Tony Gold/Sean Paul/Will Smith! He did a reggae song! Awesome!)
--Applause ("Temperaure" [Sean Paul]
--Coolie Dance (wildly popular, like "Mova Ya Body" [Nina Sky], "Feel Alright" [Sean Paul], "C**o" [Pitbull & Lil Jon] & "Pull Up" [Mr. Vegas]
--Kopa ("Straight Up!" [Sean Paul], "Turnin' Me On" [Nina Sky]

I need to learn more on riddims, since they're so intersting the rhythm.
