These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

Final Tune. Ready...GO.
Broken Base: jubeat saucer. A major part of the appeal comes from the massive songlist and constant additions of new contant. A major part of the criticism stems from its monthly deletion of songs.
Even Better Sequel: Despite its monthly removal of songs, jubeat saucer proved to be quite popular due to the constant addition of new songs.
jubeat saucer was infamous for its "song swap" system; every month, some songs were cut out while other songs are introduced or revived. The idea was to thwart Complacent Gaming Syndrome by forcing people to play different songs rather than the same ones over and over, but the mechanic still made some players unhappy. However, as of February 1, 2014, almost all previously-removed songsnote licensed songs that were removed at the start of jubeat saucer and were not revived later are still gone have been revived, and song swap will NOT be coming back to jubeat saucer fulfill.
After selecting a song on an online-enabled machine, you must wait 30 seconds for other players to join in. If you just wanna play by yourself, this can be a hassle.
That One Attack: "Riot of Color" ends with a brutal run of 24th notes that requires superhuman note-reading ability and hand speed to do. And because it comes at the end, it can be a real score killer, since it can take a good chunk out of your possible 100,000 bonus points with very few notes afterwards to get them back.
They Just Didn't Care: STELLAR WIND's Extreme chart is the just the Advanced chart rotated 90° counter-clockwise and with one note removed. It's still rated 1 level higher than Advanced. Well, it really deserves the higher rating. That turn made it a lot more awkward to play.
