This reminds me of groups/artists that felt they had to change their sound in the mid/late 70's when disco was big. Rod Stewart doing "Do Ya Thing I'm Sexy" and the Rolling Stones doing "Miss You" are two examples.
Now the big thing is dubstep, and it looks like Muse are dumping the Queen soundalike vibe, and moving into this new genre. Watch this preview below and see what you think. The new album will be called The 2nd Law, coming later this year.
