The poems listed here are from various writings of Tolkien.  Although the majority can be found in The Hobbit or LotR, some come from The Tolkien Reader.  Of course, I do plan on adding more in the future.   Note that not all the poems in Tolkien's writings have names.  I have given names to those that were without so as to make a distinction of it.

The Goblin Song

Clap! Snap! the black crack!
Grip, grab! Pinch, nab!
And down down to Goblin-town
You go, my lad!

Clash, crash! Crush, smash!
Hammer and tongs! Knockers and gongs!
Pound, pound, far underground!
Ho, ho! my lad!

Swish, smack! Whip crack!
Bater and beat! Yammer and bleat!
Work, work! Nor dare to shirk,
While Goblins quaff, and Goblins laugh,
Round and round far underground
Below, my lad!
