[Avodah] changing tune in lecha dodi

[The Goldmeiers]

I know many people do this, regardless of MO vs Chareidi leanings.
Personally, if the chazan has the kehilla "rockin" with the tune, I hate
the disruption changing the tune creates.

Regardless, My Rov recently made a statement that he wants to insists ALL
chazanim to change the tune and he dislikes it when a chazan doesn't.
he says, "it's become minhag Yisroel" to change the tune. Now my rov
is generally a nationally respected rov and poseik. When I questioned
him about the status of this strange behavior, he replied, yes, it is
now minhag yisroel and I hate it when the chazan doesn't change the tune.

So, my question to you all is, minhag yisroel? do ALL of you change
the tune? Is this early onset? (ok, just kidding on that one)

Thanks
