Hail To The Thief is indeed a dreadful album. Kid A was pretty good, but since then they've been on a downhill slope.
The first 2 albums were the best, although they were very good live on the OK Computer tour, they were still outshone by the support act, Laika. Which reminds me, you listened to those albums yet Dom? Still can't believe the crowd Radiohead drew, there was next to no-one seeing John Cale or Los Lobos, why did those two have to clash? Bloody festivals and their timing plans.
Morrissey may sound, and often be, miserable, but at least there's some humour in there.
