Given what you've got on there already, I'd say some Feeder (suggested: Just a Day, Shatter, High, 7 Days in the Sun, Yesterday Went Too Soon), The Frattellis (Chelsea Dagger, Baby Frattelli, Got My Nuts from a Hippy) and Foo-Fighters (god there are so many, Monkey Wrench, One by One, Stacked Actors, DOA??) are absoulte musts mate.
Other suggestions: Artic Monkeys, Hard-Fi, Stone Roses, Rolling Stones, The Beatles, Star Sailor, Kaiser Chiefs, Muse.
