I've been listening to Muse ever since their 1st album... Got all their albums including their live Hullabaloo album.. My fave Muse album would probably be Origin Of Symmetry....
Muse does sound like Radiohead... More precisely, when I first heard them ,they sounded like a cross between Radiohead and Nirvana.. I thought their first album wasn't that good.
As for who is better, let me put it this way; Radiohead is SUPERIOR to Muse... Radiohead is SUPERIOR than any other band... THom Yorke is GOD... 'Nuff said
