Since you made it clear only one song I will play by the rules!

Stairway To Heaven-Led Zeppelin

...Stairway To Heaven

I don't remember getting sick of that song, but would definitely lift up the needle. It became way too obnoxious 

@irjones I thought I was the only one who loves that song!  However,  I would have to say Dreams.  Close second would be Dance the Night Away, Then She Did or Three Days.

Coltrane - "My Favorite Things"
