I guess you had to have seen them live. Every song sounds the same because they use the same three chords-- not like that's a problem, plenty of great bands do the same (X, Ramones, Green Day...lets just say punk in general). Yet, I don't know, the synths don't do it for me. Your music better pretty fast or exciting or powerful if you're going to limit yourself to such a primitive chord-progression. Cogent lyrics are also never a bad idea.
