What songs go together?

For example:

Comfortably Numb – Pink Floyd
I Wanna Be Sedated – The Ramones

I’m sure there are countless songs about using drugs, so this example is a no-brainer. What other pairs (or groups) of related songs by different artists can you think of? But no fair picking songs by the same artist. The connection can be obvious, or it can be subtle and require an explanation. For erxample:

Rest In Pieces – Misanthrope
Parting of the Sensory – Modest Mouse

(Parting Of The Sensory is about “carbon’s annivesary” i.e. death, as is Rest In Pieces)
