Misc Christmas - Jingle Bell Rock chords

Hey guys, so I was on here trying to look for chords for this song, but all of them seem 
slightly off (especially on timing) so I tried to make my own version with timing 
included and I think it works. Hope you enjoy and happy holidays!

Jingle Bell Rock


D            DMaj7        D6          F#m
Jingle bell, jingle bell, jingle bell rock
D6           F#m       [ch]A7sus2[/ch]       A
Jingle bells swing and jingle bells ring
Em          A          Em          A
Snowing and blowing up bushels of fun
E7                 A7
Now the jingle hop has begun

D            DMaj7        D6          F#m
Jingle bell, jingle bell, jingle bell rock
D6           F#m      [ch]A7sus2[/ch]      A
Jingle bells chime in jingle bell time
Em          A           Em           A      E7
Dancing and prancing in Jingle Bell Square
       A7     D  D7
In the frosty air.


       G                     Gm
What a bright time, it's the right time
   D
To rock the night away
       E              E7          A
Jingle bell time is a swell time

To go gliding in a one-horse sleigh


D        DMaj7         D6           F#m
Giddy-up jingle horse, pick up your feet
D6      F#m       B7
Jingle around the clock
G                     Gm
Mix and a-mingle in a jingling beat
E7            A7          D
   That's the jingle bell rock


E7            A7
   That's the jingle bell,
E7            A7
   That's the jingle bell,
E7            A7          D
   That's the jingle bell rock
