Contrary to popular belief, Billy Squier is not dead. In fact, he's still making music. None of his new music has the same impact as "The Stroke", which is an absolute classic song. And the fact that he's still around is not the only thing that goes against popular belief.
This song is absolutely not about masturbation. Of course, everyone thinks it is, but the reality is, it is about the music industry and how artists need to sell out to make it. Ironically, the song became a top 20 hit, probably because everyone thought it was about masturbation.
Regardless of the subject matter, it's a great song. Breathe it in.
