Easiest songs to play in drop d on electric and/or acoustic?

well i haven't been playing for a long time but what are some easy drop d ones?
Damned If I Do Ya (Damned If I Don't) - All Time Low
Circles - All Time Low
The Beautiful People - Marilyn manson
^^ All in Drop D
Before I Forget - Slipknot
^^ Drop B
Animal I Have Become - Three Days Grace
^^ Drop C

But like just extra stuff:
king of the hill theme song
halloween theme song
Anyone esle know some easy ones? I can also use Standard as well, drop c, or drop b but not very fond of drop b xD

 

I don't get whats so special about drop D.. but:
Killing in the name - Rage Against the machine
Americana - The Offspring
96 quite bitter beings - CKY

 

Brainstew by Green Day is really easy to learn, and it's alot of fun to play too!

 

well mainly not necessarily special but just more of like its easy to go back to standard with drop d because only the top string is dropped and not as much of a hassle as much atm since i tune by a online guitar tuner and stuff.

will try it out

 

what i mean is why someone would prefer drop d so much more than standard.

 

Smoke on the water (on top string).
