They been adding a lot of Bob Marley songs to the DLC. I like them, but there's more than one band from Jamaica.
Why not Toots & the Maytals? They are one of the all-time great groups from the island. The addition of keyboard and harmonies to RB3 would make their stuff fun to play; obviously their songs would not be challenging to hardcore RB3 players, but people like me who enjoy sitting back and playing the Bob Marley songs would like this.
