Your favourite Reggae / Dub / SKA tracks

Trying to make a "white reggae" Pandora station and it just doesn't get it. I keep adding "variety" using songs, mostly by the Police, and it's playing crap like "One of These Nights", Van Morrison, Red Hot Chili Peppers. I've thumbs downed a ton of songs.

Message In A Bottle- The Police
Armagideon Time- The Clash (ska)
Walking On The Moon - The Police
Every Breath You Take - The Police
