So, I did a run of All S-Ranks on Normal mode. The category is self-explanatory, but just in case: Create a playlist with all songs, and get an S-Rank in all of them. If you fail, restart the track until you get it. (That means you can keep trying, the run doesn't die if you get hit.)

Here's the link to the run (Mortal Kombat got silenced, so I'm uploading it to YouTube as I'm writing this):

I'm not sure if this could become an actual category or not, it's pretty much the equivalent of a 100% category.

Also, if this gets added, a subcategory for Normal/Hardcore would need to be added, but that's about it.

As of improvements on the run itself, here are the main timesaves from my run:

• Failed Termination Shock around the middle of the song.
• Failed Lycanthropy three times at the beginning due to me being bad.
• Failed Wicked twice at the first checkpoint mark.
• Failed Paper Dolls three times on the first half of the song.
• Failed at the very beginning of Commando Steve.
• Failed around the middle of Tokyo Skies.
• Failed Dance Of The Incognizant twice because I tried to do the cheese.
• Failed twice at the very end of Fox.
• Failed three times around the middle of Core.
• Failed a grand total of nine times on Mortal Kombat because I'm bad at this game.
• Failed three times on Deadlocked.
• Failed Strike The Earth! at the second checkpoint.
• Failed In The Halls Of The Usurper almost at the end.

All in all, sub 2h is possible. Thoughts?

Here's the YT video, in case you want to listen to Mortal Kombat for 10 minutes:
