Well, looking at your previous three posts, it looks like you are a lurker considering your join date of January 2010. Radiohead being a good band is matter of opinion.
The reason I added the first sentence/disclaimer is because of people who have the hardcore attitude that metal is the only good genre of music and that everything else sucks. The only conclusion I can draw from that attitude are that those people aren't well rounded.
Metal is phenomenal, but there are many other decent genres too.
