In Flames. \m/
Edit: So many ppl are naming In Flames but name some of their crappier songs imo. Cloud Connected? Eww.
But that's just me. Off the top of my head I'd prefer System, Only for the Weak, Dial 595-Escape, Borders and Shading, Brush the Dust Away, Ordinary Story, Dead Alone, and F(r)iend isn't too shabby either. I've got all their songs on my ipod though
Edit2: Children of Bodom is very nice also. Needled 24/7, Are you Dead yet?, etc.
