Consider the song "Let Down" off of Radiohead's Ok Computer,

and compare it to Toots and the Maytal's "version", "Let Down."

Here are the lyrics to "both" songs.

Transport
Motorways and tramlines
Starting and then stopping
Taking off and landing
The emptiest of feelings
Disappointed people
Clinging onto bottles
And when it comes it's so so disappointing
Let down and hanging around
Crushed like a bug in the ground
Let down and hanging around
Shell smashed, juices flowing
Wings twitch legs are going
Don't get sentimental
It always ends up drivel
One day I am gonna grow wings
A chemical reaction
Hysterical and useless
Hysterical and
Let down and hanging around
Crushed like a bug in the ground
Let down and hanging around
Let down and hanging
Let down
Let down
You know, you know where you are with
You know where you are with
Floor collapsing, floating
Bouncing back and
One day I am gonna grow wings
A chemical reaction
(You know where you are)
Hysterical and useless
(You know where you are)
Hysterical and
(You know where you are)
Let down and hanging around
Crushed like a bug in the ground
Let down and hanging around

Questions: (a) Are Radiohead and Toots and the Maytals two recordings of the same song or are they recordings of different songs? (b) Regardless, how do Radiohead's original and Toots and the Maytals' remake differ? (E.g. is one sadder than the other? Does one seem "truer" to the lyrical content?)
