American vs. British Alternative/Rock

So... my roommate's mad into Angels and Airwaves. And so I listen to it like 5 times a day too. (He doesn't use headphones.) It made me realized that I personally like Brit rock a lot better. The difference is that American bands/singers like to raise their voices by a pitch or so (think Blink 182), while Brit singers drag their voices (think Stereophonics, Oasis, Coldplay).
