And his point is that since Muse aren't lazy in nearly any other regard as a live band, the lack of variety probably isn't due to laziness. It's not laziness that makes them rehearse a rarity to play for a couple of gigs in Europe or Asia and then drop it in the US. That's not how it works.
This "whatever reason" has been explained by Muse themselves several times. Trust me I think it's really stupid of them, but it's certainly not laziness. Matt has even complained after gigs in the US because they only react to the pop hits. What you said originally was that people wouldn't "stand there with their hands in their pockets because a song they don't recognize is being played", but that's exactly what the majority of the audience has done whenever a rarity has been played.
Probably not, no.
