i totally agree... i think clocks is my favourite one, but everyday i find something new in every song.. f.e. life in technicolor is a great great opener/closer......
very very easy radiohead songs:
-creep (only 4 chords)
-lucky (good for changin' chords)
-the bends
-street spirit (good for your arpeggio practise...)
-karma police
-no surprises
-how to dissapear completely..
-nude (fairly easy to play, difficult to sing..)
and i think coldplay's lost is also very easy...
good luck!!
p.d. i recommend u this link: ultimate-guitar
easy!!
for the correct tabs i recommend you:

but you can find the sheets over here:
HTTT, Pablo honey, KID A

Hope the links works.... if they dont then i recommend you the big universe of google...good luck...
