Metallica - Enter Sandman

For anyone here who was working in radio in 1991 when this song was on the charts, did this song get any airplay? I imagine it would have been considered too hard even
for Top 40 radio, but I suppose some stations may have played it at only certain times of the day. Also, if it did have some airplay, was it the Album/Single Version
that was played or the Radio Edit running about 4 Minutes from the Promo CD Single? I know the song got up to #16 on the Hot 100 and I'm sure the majority of its chart
points came from Sales. I can honestly say the only time I heard it on the radio was on "American Top 40" with Shadoe Stevens.

I know Shadoe Stevens played it during its chart run, however, it was severely edited and I think it ran around 2 minutes.

That’s the official edit. The intro is unique; it’s a new mix from the
multitrack rather than a straight edit. Beyond the intro, nothing else
stands out to me as being different with the mix, but I’ve never done a
close A/B.

The bulk of my memory of this song did come from MTV. I was not
a big Metallica fan nor were my friends until this song went into
heavy rotation on MTV. Aaron are you saying just the intro is a new
mix or the entire song?

I tried to A/B this track and the edit sounds like a hotter mix to
me but I'm far from an expert. Plus I'm using a YouTube source
since the promo CD is so expensive. I do like how the intro is
exclusive to this edit but man it tears the buildup down so much.
That song is all about the buildup to the first verse. They also
cut 4 bars out after the first chorus. In addition they fade the
song out early and I love the long fade on the album version. If I
were to edit this track I would probably try not to mess with it too
much. Tomorrow I'm going to make an attempt at the following
for the intro:
leave first 4 bars
cut second 4
leave 8
trim next 12 down to 4
trim next 8 down to 4
and not touch the rest.
