What song have you played the most?

The Beatles, “Revolution #9”...

Backwards of course.

May be a tie with my first 45 rpm single that was the theme song to the TV series Cheyenne (it was the only record I owned for 6-7 years, so it got played a LOT).

theme song to the TV series Cheyenne

That's going back quite a bit. I watched the show as a kid and stream it  quite regularly now  on Philo. I hadn't seen it in years til recently.

Just as I am.

I’ve heard it 10,000 times if I have heard it once, AND If I’m lucky I’ll hear it 10,000 more times..

Like my Grandmother use to say "If the Good Lord don’t come or the creek don’t rise".. RIP 1889-1988 (99 year old).

Then she went to heaven.

We also watched Gunsmoke every Saturday night and Have Gun Will Travel.

They were all reruns as I was born in the mid 50's.

6 months into the pandemic I watched the entire "The Office" series from the first to last episode (in order).

I was much better than I ever imagined.

Tried the same with "Friends", but gave up after 2 episodes.

If I go back over the years, I would guess it would be the greatest Rock & Roll song ever written and recorded.  The anger and violence till drips from the song.  Powerful lyrics that still ring true 50+ years later.  A searing guitar solo that barely consists on more than one note.  Vocals ending in that great falsetto.  Yup, that would be the one song for sure.
