Please help!! There is a song that has the lyrics "I like mmmmmmmmm with you"
it was a popular song about 5 years ago. The song repeats the same lyrics over and over for about 2 minutes. I have a bet on with my new brother in law that this song actually exist . If I can find it he will sing it in a public area of my choice.
I do not know the artist or the song title. The singer sings the lyrics over and changes the pitch and tone as the song goes on.

Reminds me of a comedy routine from the late 1970's by Martin Mull called "The Humming Song"

Last night I took you home
And we began to hmmmmm
You were such a hmmmmm
Hmmm hmmm hmmm hmmm only seventeen
Hmmm hmmm hmmm leather skirts
Hmmm hmmm hmmm rubber shirts
Hmm hmm hmm hmmmm and jars of Vaseline

Hmmm hmmm hmmm hmmm hmmm hmmm
Hmmm hmmm hmmm hmmm -- pick up the soap!
Hmmm hmmm hmmm hmmm -- mayonnaise and rope!

Then from the chandelier
The three of us did hmmm hmmmm hmmmm
Hmmm hmmm hmmm hmmm
Hmmm hmmm hmmm hmmm hospital for life
Hmmm hmmm hmmm whips and chains
Hmmm hmmm hmmm Great Danes
Hmmm hmmm hmmm hmmm your wife

Maybe it's the song called "I wanna mmm" by Lawyer?

I like this one:
