I also would buy any album Anti Flag puts out, it is great music and they have a message to get involved, otherwise nothing changes / none of the studio songs stand out as better then the others, it is just a very good consistent effort, and I love the advice for GW / If your an Anti Flag fan, then you will love this album / even if you aren't, it is a good intro to Anti Flag that benefits multiple charities.
I'd buy anything they put out, so I'm biased. If money is tight you MUST download "Paradise" which is a classic. The other 4 studio songs are quite good (the 2 interludes are, well, they're brief so you don't really have time to reach for the skip button) and the sound quality on the live recordings is excellent.
