I've gone ahead and searched through all the archives with OpenIV and compiled & organized all the music events that could be found in this archive here: https://cdn.discordapp.com/attachments/1008390617971294300/1011765850002432090/Music_Events.7z
They're split in folders titled respectively to their DLC folder in the files, some of you may find those useful. I also went ahead and removed all the events with _MOOD, _MD and _MA since they don't seem to do anything in-game when tested.
(Also Lowrider tracks utilize Heist events so that category features the "Start" for Lowrider tracks and Heist triggers for the intensity variants)
