Yeah it's in that long ass video along with those other bugs under it. I'll add some time stamps in observed result to help any checks.
After the bonus stage where you ride the never ending story refrence, the music didn't go back to the harrier theme it just went mute.
Hang-On tape I already checked that and the jukebox tune in you arcade, they are still not fixed.
On a side-note some of the music that was bad in Shen2 is improved in a few places like Queen.St day but I wouldn't say it's fixed, just hella lot better to what it was.
I will make a video of a few tunes in 1.0.2 later that I think need checking, since you can turn off the sfx in these ports to hear the music clearly without background cluter sounds.
It might be the X-mas/New Year themes you heard, that play around Dobuita during that time. I had trouble finding videos of the dreamcast version to check if these are playing back wrong in the ports or if that's what they sounded like, some sound okay, others not. Several locations play different festive jingles.
