Hip Hop elements? Are you sure you're talking about System of A Down here? I can think of very few instances when pseudo-hip hop elements are used to add a bit of exotic flavour to a song, but there's certainly no way you can broadly classify them as a band that generally "combines hip hop with metal", that's more appropriately used to describe bands like Korn, Limp Bizkit, etc. Their original-sounding style combines tight thrashy metal with more melodic parts and of course the unique vocal style, as well as lyrics that are (generally) far more meaningful than those you can find in 90%+ of death/black metal these days. SOAD rocks!
Grow up already.
