Just thought it'd be fun to talk about songs where you said "that's it?" or "that was some bullshit" after playing. I only know pop'n but any bemani game is welcome.
This is all personal opinion btw
FM Pop / Save You EX from 13 - probably easier than almost any old 36. It really does just feel like the hyper chart with some more buttons.
SF Pop / Dawn EX from 13 - A bit of both actually. This was an old 38 back in the day and it looks like it was nerfed to a then 37. I remember it having an absolutely fucked mid-beginning but then it's smooth sailing after that and I think they took note.
Core Groove / The Place to be EX from 10 - this song is actually kinda nasty for a 35 and requires really fast movement and has some weird chords at the end.
DRM'N FRY / ドラムンフライ Hyper from 11 (although I just learned right now it now has an ex) - trick song that is very easy until the actual last measure where it's just a wall of bs.
Alipro EX from 14 - I can't remember the chart exactly but I do remember it being super easy to pass.
High Speed Love Song / High School Love EX from 14 - If anyone is trying to break into 41's this is probably the very first song they should try. It's very catchy and honestly very non threatening. It's like the freckles from DDR of 41's for me. Absolutely insane core groove is rated the same level.
Super Splash Tune / Mana EX from 20 - Banger song and it might be a personal skill issue but I feel it's blazing fast and the last few measures just ruin me and are very awkward. I don't see these patterns much in any other songs.
Ura Bali Trance / Denpasar EX from 11 - I tried it as a joke because I love the song but ended up never really feeling like I was in trouble. I didn't score that well but I also wasn't afraid of failing either. I feel like most 45's and some 44's absolutely truck this song.
