This whole album is great, and while I plan on listening to all the other ones and stubbornly refusing to refer this one since everyone else seems to, I did choose to start here. And this is one of my favorites, along with Rejoice, and Brave as a Noun.
If you don't know Andrew Jackson Jihad, this would most closely be categorized as folk punk, which basically means punk-y attitudes with folk-y music and voices. But if you're a fan of emotional lyrics about life, folk-y sounds, and/or rough, imperfect vocals give the genre and Andrew Jackson Jihad a try. He's probably the most well known.
I just love the opening to the song, both the lines and the tune and the vocals. "I gave birth to twin wire hangovers/and now I am a personal space invader." I have no clue what he means really, but it's great.
