Yeah. I absolutely loved how ECW used commercial/licensed music. Scorpio coming out to Whoomp by Tag Team or Kool & Gang's Jungle Boogie. RVD with Pantera.
It was great. WWE removed the music from the ECW DVDs as well. Though Pioneer mostly removed or much trimmed the music on the ECW DVDs even when ECW was still around.
Anyway, I think the music was a big aspect to ECW and a not insignificant part of why it and certain wrestlers were cool and so loved.
Very interesting. Growing up, I always just assumed they used the actual songs legally. Being older and wiser now, I should have figured that that was unlikely given the costs. So it is amazing how Heyman got away with using what he did.
