i can do a few of those
oasis
ocean colour scene
are both british trad rock.
blur (old stuff) is the definitive britpop.
(new stuff) maybe alternative (i dunno)?
isn't supergrass britpop? (i dunno about this one.)
nirvana is definitely grunge. so is pearl jam.
i think blink 182 and green day are technically called punk revival, but i dont know why, as punks detest both of these bands.
sum 41 wants to be a heavy metal band, modeled after iron maiden.
yes, i am quite bored right now

peace
listen to me on georgetown student radio. every monday, 8-10 pm (eastern) sometimes i'll spin if the equipment's working, otherwise it's some laid back grooves and good indie rock. check it out!
