Understand Music

Nicely done. By finally. (their name actually has a full stop at the end so I don't know if I should also put one at the end of the sentence, like 'finally..')...

The Motherhood Rap

Like The Swagger Wagon, but just for Mums (and for Fiat, not Toyota). Good lyrics ("Work versus home is a mental combination, with my elbows deep, in infant defecation"), and good for them for finding someone you don't want to punch. Must have been hard. 

Metallica Soundboard

Actually it's just James Hetfield, but still. Brilliant.
