The Vault Series DVD from Universal replaced a significant portion of the music. I would estimate about 40%. I was under the impression that the Cinemax HD broadcast had the original soundtrack. Prince, Madonna and Billy Idol for example... they're all there on the HD version. Eddie Van Halen's music remains in the Vault Series DVD but a few cues seem to be moved or added when compared to the HD broadcast. I really don't know because I mostly saw the film on pay cable in the '80s. I did see it in the theater, but there's no way I can remember the music cues. Cinemax usually shows the theatrical prints even if the film isn't released on optical media, but who knows? The songs do match what's listed in the end credits on the Cinemax broadcast. There were other examples of song replacement in the early days of VHS. Sixteen Candles did that. Later on DVD and Blu-ray, the soundtrack was restored. Fast Times also had songs replaced on VHS. But the Blu-ray is now intact. I guess some copyrights are negotiated for theatrical and television broadcasts, but not for home video/digital.
Found this...
"From what I understand, the MOD DVD features the "rescored" soundtrack that has been available on all previous home video versions of the film. The "home video version" had several songs removed or changed for licensing reasons--all or most of these spots were filled by reusing portions of Eddie Van Halen's score. Contrary to some posts you might see online, Eddie's score has never been replaced on any version of the film. Going by memory here...but some of the songs replaced include Madonna's "Burning Up" and Prince's "Dirty Mind."
Contrary to the DVD, cable airings, including recent HD broadcasts, include the full, original theatrical soundtrack. If a Blu-ray is simply going to re-create the "home video version" soundtrack, which the MOD DVD apparently does, then I have no interest."

Based on this information, it seems that Team Blu's version features the original soundtrack.
