I think it's a great collection. It has fewer BGM tracks than the previous releases, so whether or not that's good depends on your preference. Some of the songs have newer versions, like MEGARE is a group version while previously I think only solo versions existed? Of course the premiere songs are Jibun REST@RT and Marionette no Kokoro. There are two bonus tracks; a 16-minute one that sounds like an audio drama, and a 10-minute one that actually is just clips of all the songs that played during the episode 13 concert (not as unique). The BGM tracks that are there are good ones in my opinion; they're the quiet and melancholy Aoi Tori and GO MY WAY!!.
