I think I like it more when it's from a past era, or maybe I simply enjoy songs that are social criticisms and not political ones. Politically influenced music from 30 years ago can be pretty interesting, but I don't like current stuff that much, because you pretty much know it's going to be "I hate George Bush blah blah oil blah blah etc." I might agree with it, but I don't think it's really very interesting to listen to.
