Cghost, the closest thing to what I was really looking for was your Against Me! suggestion.
As far as metal stuff goes.. 40 Watt Sun, Loss, The Angelic Process, and Warning. Outside of metal... stuff like Carissa's Wierd, Giles Corey, can't think of any others atm. They put their sadness into the songs and is passed on to the listener.
