Best album is Make Sound. This is one of those bands that never disappoints, but also never blows you away. Way better than the Dopamines, who sound like a rip off of the Copyrights and I never liked.
But if you are looking for really good pop-punk, head over to punknews.org, search by bands for the "Mean Jeans", and stream their most recent album. It was my album of the year. Stream has been up forever.
