First one and so I'm sorry if it's not great or if I mistaked any lyrics, I got them from a website. 

* = strum once

G* C* Em* (x2)

G*                C*                  Em*
   That slow burn waits while it gets dark
              G*
Bruising the sun
             C*                  Em*
I feel grown up with you in your car
                
I know it's dumb

G  C  Em    G  C  Em
Oooooooooooooooooohh


G*               C*                    Em*
   We both got a million bad habits to kick
                G*
Not sleeping is one
                 C*                      Em*
We're biting our nails, you're biting my lip

I'm biting my tongue
G  C  Em   
Ooooooohh
G                      C
But people are talking, people are talking
Em                     C
But people are talking, people are talking


G                        C
Raise a glass, cause I'm not done saying it
Em                       C
They all wanna get rough, get away with it
G                         C                     Em
Let 'em talk, cause we're dancing in this world alone
Em                 G*
World alone, we're alone


            C*                       Em*
All my fake friends and all of their noise
               G*
Complain about work
                 C*                    Em*
They're studying business, I study the floor
                                    G*
And you haven't stopped smoking all night
          C*                Em*
Maybe the Internet raised us, or maybe people are jerks
G                     C
But people are talking, people are talking, but not you
Em                    C
But people are talking, people are talking


G                        C
Raise a glass, cause I'm not done saying it
Em                       C
They all wanna get rough, get away with it
G                         C                     Em
Let 'em talk, cause we're dancing in this world alone
Em                 G
World alone, we're alone


G                    C
All the double-edged people into schemes
Em                        C
They make a mess, then go home and get clean
G                               C                       Em
You're my best friend and we're dancing in a world alone
Em                        G*
A world alone, we're all alone


C*   Em*


             G*   C*     Em*
I know we're no-o-ot everlasting
        G*   C*               Em*
We're a trainwreck waiting to happen
            G*   C*             Em*
One day the blo-o-od won't flow so gladly
         G*       C*  Em*        C*
One day we'll all get still, get still


G* C* Em* (x3)


G                        C
Raise a glass, cause I'm not done saying it
Em                       C
They all wanna get rough, get away with it
G                         C                     Em
Let 'em talk, cause we're dancing in this world alone
Em                 G
World alone, we're alone


G                    C
All the double-edged people into schemes
Em                        C
They make a mess, then go home and get clean
G                               C                       Em
You're my best friend and we're dancing in a world alone
Em                        G*       D      Em
A world alone, we're all alone

G  D  Em
