Do you think these songs fit the novel 1984?

They do fit, especially the Muse songs. Actually, I've seen interviews about Matt Bellamy (very big Muse fan) saying that Resistance IS about 1984 (just in case you didn't already know ;) ), but that another one of their songs, Citizen Erased, is ALSO about 1984! :P You should add that one to your list, hmm? :)
