love how it just comes in - POW! nice dark vibe which works for me. drums and bass sound ok on my behringer truths, but in the chorus i'd have somthing else to layer with the guitars, either an electric rock guitar (maybe playing a chiming lead a la kings of leon/coldplay) or some kinda organish synth, whilst the drums and vocals signal the chorus, it needs more melodic oomph.
nice singing, and it certainly doesn't outstay its welcome!
