Oh Wiki...
"Groove Is In the Heart" is a funky, cheerful[citation needed] love song that compares the new feelings of infatuation with hearing a good ("groovy") song.
I suppose it's true that "cheerful" is a subjective property: what cheers you might dispirit me. But, a citation won't solve that problem; a citation here just would just substitute somebody else's subjective definition of "cheerful" for the Wiki author's subjective definition. And then where would we be? We'd be nowhere, that's where.
On the other hand:
The depth of hula groove
Moves us to the nth hoop
We’re going through too
Horten hears a who-o-o
I couldn’t ask for another (I-I-I-I)
No, I couldn’t ask for anotherDJ Soul was on a roll
I’ve been told he can’t be sold
He’s not vicious or malicious
Just dee-lovely and delicious
I couldn’t ask for anotherGroove is in the hea-a-a-art
Groove is in the hea-a-a-art
Groove is in the hea-a-a-art
Groove is in the hea-a-a-art
Oh yeah, that shit's cheerful. I dare anyone to say different.

My love for that song is matched by my scorn for the pedantry of some Wikipedia editors.
tis a great song.
