This is Shake it out, originally sang by Florece + The Machine.
I really like Glee's version so here it is for you all!
So this is the short version they sing on the show :)
capo on 3
( D )
Regrets collect like old friends
Here to relive your darkest moments
( G )
I can see no way, I can see no way
( D )
And all of the ghouls come out to play
Bm G D
And every demon wants his pound of flesh
A Bm
But I like to keep some things to myself
G Em
I like to keep my issues strong
G
It's always darkest before the dawn
D
And I've been a fool and I've been blind
G
I can never leave the past behind
I can see no way, I can see no way
D
I'm always dragging that horse around
Bm G D
And our love is passed, it's such a mournful sound
A Bm
Tonight I'm gonna bury that horse in the ground
G Em
So I like to keep my issues strong
G
But it's always darkest before the dawn

D
Shake it out, shake it out, shake it out, shake it out, ooh woaaah
Shake it out, shake it out, shake it out, shake it out, ooh woaaaah
G
And it's hard to dance with a devil on your back
D
So shake him off, oh woah
Bm G
And it's hard to dance with a devil on your back
D A
And given half the chance would I take any of it back
Bm G
It's a final mess but it's left me so undone
Em G D
It's always darkest before the dawn
Bm A
Looking for heaven, for the devil in me
Bm A
Looking for heaven, for the devil in me
G
Well what the hell I'm gonna let it happen to me
D
Shake it out, shake it out, shake it out, shake it out, ooh woaaah
Shake it out, shake it out, shake it out, shake it out, ooh woaaah
G
And it's hard to dance with a devil on your back
D
So shake him off, oh woah
D
Shake it out, shake it out, shake it out, shake it out, ooh woaaah
Shake it out, shake it out, shake it out, shake it out, ooh woaaah
G D
End!
