I first heard this song on the cassette release of the Crow soundtrack. Up until then I had only heard the chorus on the trailers for the movie, and so when the track started playing in my car while leaving the mall I bought it from, I was confused as to whether or not it was the STP track. The whole tone of the song is different than what you'd imagine from hearing only the chorus.
It's still one of my favorite STP tracks of all time, and because I was indoctrinated to it from the Crow soundtrack, I always felt that it flowed better on that album than it did on Purple.
On that note, the Crow is getting a limited RSD 2-vinyl set release this year. I'll definitely be picking it up.
