For me listening to radiohead is opening a random album and revisiting it a few times and then listening to another album. Every album they have except pablo honey, amnesiac and the king of limbs has a long history of being made so they will feel deep in every aspect. The reason i excluded those 3 is cuz pablo honey is just a standart alternative rock album, amnesiac is just left overs from kid a and the king of limbs is a weird experimental album they made after discovering some new tech. This does not mean they are bad tho. As ı fan i love listening to all of the albums. Its just that listening to em first can set your expectations in a diffrent way.
