Yeah I like Lamb of God but for some reason I never really enjoy them enough to listen frequently. Testament is probably my favourite thrash band and yeah, first time I heard Laid to Rest I picked up the similar riffs - although they created their own interpretation of it so it doesn't really bother me.
Also it doesn't really bother me who rates it or if there's repeat ratings, feel free. I enjoy the format of people sharing their own tastes and briefly commenting on the tastes of others regardless of how many people participate.
