Audacity + She is Legend = Heaven:

The big problem holding back the quality of She is Legend songs is the 'screamo' portions, where the melody ends and for about ten seconds at a time a person screams into the mic meaninglessly.  There's actually a good reason within the plot for the music to do this -- Karen has a split personality and both sides like to sing during the concert, which means the crazy killer also gets to have her time in the sun -- but musically it's a disaster.

The solution is to use the Audacity music editing tool to edit out all those sections.  Once all the screaming is gone you're left with just a pure Jun Maeda melody, no different from Girls Dead Monster.  I've edited all the She is Legend songs into their true, musical forms, and that's why I can rate them so much higher than before.

I also promoted Shiva and Musica Caelestis to 5-star ratings, demoting Ankoku Outei Beld's Te-ma and Unused Shop to 3-star to keep symmetry.  Since Ankoku and Unused both had names attached to them I also had to edit my '100 Waifus' music playlist.  I moved Kenpachi's song over to Boss Battle 2 from Chrono Trigger (fitting since Kenpachi was one of Ichigo's Boss Battles).  And I moved Benno's song over to 'The Trial' from Chrono Trigger (fitting since Benno seems to always be sternly judging Myne).

Miharu (from Da Capo) received Musica Caelestis as her new theme song.  Shiva was already Rumi's theme song so nothing changes with its promotion to 5-star.

Thunder Cat Byakko is now fully enhanced, which means all my Memorias are fully enhanced again.

I've finished my rewatch of 100 Girlfriends S2, Ao no Hako, Grisaia Phantom Trigger and Ave Mujica.  Rewatching didn't make me like the shows more, but it did prove they were rewatchable, which proves that rating them as 'great' wasn't mistaken.  All that's left to rewatch is DanMachi S5, FT 100 Years Quest, Monogatari Off Season, SAOAGGO S2, and Bleach TYBW S3.  (Plus shows that are currently airing, which it would be pretty silly to be 'rewatching.')  All of these are sequel seasons, with their core works already rewatched and their quality already assured, so rewatching them hardly even matters, but I'll do so anyway for the sake of thoroughness.

The amount of great anime coming out in the past years has shrunk, so it's becoming more and more possible to fulfill my promise of watching and rewatching all great anime in full to prove it really is great.

Most high-level entertainment these days consists of video games, not anime.  I'm almost done rewatching anime, but the list of games I still need to play is endless.
