I like Clash skank: Paul Simonon is one of few punk bassists with the right feel.

The one I really love, however, is their version of Willi William's Armagiddeon Time, also off Black Market Clash.

The whole reggae/dub thing was the Achilles heel for the Clash. They didn't have the rhythm section to pull it off and it just made them sound weak compared to their influences. Still pretty good.
