go ahead people laugh while you get the chance,
Linkn Park "Numb" is a good one not sure if this fits your bill.
If you want unique go for some celtic-music!
For this I suggest Dulaman by the Celtic Woman group....or
Mo Ghile Mear By the Chieftans
All I can tell you about these songs is that the 1st talks about Seaweed.
The 2nd one talks about war basically, in the sense that you are morning the bastards who were lucky enough to fall before you.
If you are interested in another unique one that really stirs my blood comes in the form of Sgt Mackenzie's Lamentation.
I hope these are unique enough for ya.
