The majority of owners, if they elect to change the songs, will likely opt for the older, non-remastered versions of the same songs. Some folks may change out songs altogether, but the DMD animations are kind of tied to that specific song.
I'm going to change as many as possible as long as the length is the same. After a quick review, it's maybe 50%. I'll also change Dr. Love to God of Thunder and change the match sequence song.
Hopefully will update by this weekend, so I'll report back.
