One of the greatest modern punk albums I've heard, it's very positive, uplifting, fun to listen to on a sunny day, and a go-to album if I'm having problems in my life. I strongly suggest you listen to this, because you'll be singing along and humming those clean, amazing melodic guitar riffs in no time.
By far my favourite album by this band. Walter S did the production and it just changes the approach. This stands apart from all their other albums alone. It is almost a different band, and a great one.
