This isn't technically The Swellers but it's done by Nick Diener, so it sort of still is them?
It's still a fun song to sing to your lady friend and pretty easy and corny.

   C                 G                 F
I know it's lame but my heart skips a beat
           C                    G
when your name shows up on my phone
     C              G         F
And I've never met anyone so sweet.
           C                   G
You're the greatest I've ever known.
         F                                     G
And to write this song, it didn't take too long.
               C                G                 F
It's easy 'cuz I love you, yeah I love you, yeah you
C                G                 F
I blame you when I can't sleep at night.
          C                G
You're on my mind all the time.
     C               G        F
And every year when February comes
       C                 G
I will have the best Valentine
        F                                       G
In the whole wide world, you're my favorite girl.
               C                G                 F
It's easy 'cuz I love you, yeah I love you, yeah you.
               C                G                 F
It's easy 'cuz I love you, yeah I love you, yeah you.
               C                G                 F
It's easy 'cuz I love you, yeah I love you, yeah you.
               C                G                 F
It's easy 'cuz I love you, yeah I love you, yeah you.
