Real Power

In Adventure Time season 5, in the episode "The Great Bird Man" Finn and Jake meet the former goblin king Xergiok, that during a scene in which they are flying on a huge bird, he sung "Real Power", a quite trippy song in which he has some awesome allucinations :D Here are Real Power Song's lyrics:

Far, far above,
Time standing still,
Memories are One,
Same space, same will.
Now move along,
Light speed divides,
Rips all from One
It blows my eye-holes
and fills me with real POW-ER,
fills me with real power,
power power power power
Power...

Bread Song

In the episode "Jake the Dad" from Adventure Time Season 5, BMO is playing the Bread Song to Finn  while dancing with a couple of bread slices. When Jake comes back at home, he founds them in a rather awkard scene. Does BMO's pad taste good? :O Here are Bread Song's lyrics:

I said to the bread lady
What happened to your husband?
Is he bread?
Is he bread?
I've got all the bread you need!

Where Everybody Knows Your Name

In the episode "Simon & Marcy" from Adventure Time season 5, the young Ice King when he was still known as Simon, is trying to save little Marceline from a group of mutants but as he needs his crown to use the ice powers, he needs to sing a song to try to remain sane. The song he sings in this episode is "Where Everybody Knows Your Name" that he sung before to have fun with little Marcy! :D This was really a great episode, i'd love to see more from the early life of Simon Petrikov / Ice King. Here are Where Everybody Knows Your Name Song's lyrics:

Making your way in the world today
Takes everything you've got.
Taking a break from all your worries
Sure would help a lot.
Sometimes you wanna go
Where everybody knows your name.

Version 2:

Making your way in the world today
Takes everything you've got.
Taking a break from all your worries
Sure would help a lot.
Wouldn't it be nice to get away?
Where everybody knows your name.
Where everybody...
