This is a great mash-up because it works on several levels:

It’s seamlessly edited. The two songs meld and build on each other. It has an organic dynamic.

A mash-up can editorialize and this one does so with style and intelligence. In juxtaposing very different musicians from distinctly different cultures, but who draw from similar wells of inspiration (politics and social commentary), it celebrates the unifying power of music and it specifically reminds us of the vital link between punk and reggae. It makes a statement beyond the statements the songs already make or re-enforces the statements made… or both. In this case, the songs share a deeply cynical view of any kind of quick spiritual fix, religious or otherwise.

It takes two really good songs and combines them to create another really good song.

It fucking rocks and it brings a smile to my face.
