Misunderstood song lyrics and how they can affect your perception of love

A few years back, I read the book Namedropper, a cute little British novel about a teenaged girl whose jaded view of love is based on these Don Henley lyrics:

And I can't tell you my love for you will still be strong
After the boys of summer have gone

Except, if you know Boys of Summer, you know it's I CAN tell you, which she finds out at the end of the novel. I thought of this because I just got done listening to Sometimes Always by Jesus and Mary Chain (with the angelic Hope Sandoval). For a very long time, I thought the last bit of the song was:

I got down on my knees
And then I begged you please
I'll always need you, take me back

I thought, okay, he went away. But now he's back! Then much later, I found out it's actually I always knew you'd take me back. And that just changes the whole song, doesn't it?
