Sure Know Something Lyrics

Cover art for Sure Know Something lyrics by KISS

After I heard this song the first time--it was on repeat in my car for a week straight.
As for the lyrics--Here's what I'm thinking: This woman broke this guys heart, but he just can't come to terms with it--and can't figure out why--but it's Something.

It's like when a friend asks you, "What is it about them--Why are you so hung up on them?"

And you go "I dunno, dude--but I sure know something.."

haha, does that make any sense?
