Self explanatory. Let's see if we get some really strange ones from you guys. Mine was Black Sabbath - NIB. I remember I heard that song when I was 12 and told my parents "I want to learn guitar!" Then my dad laughed and told me it was a bass. Then I said "I want to learn bass!" Took me a few years to be able to play that off rhythm intro, but the rest of the song wasn't bad too bad for me.. Funny to think back on that.
