* NightmareFuel: [[https://www.youtube.com/watch?v=CGAzBm8_QZ8 Joubutsu2000]]. The lyrics itself are about [[spoiler: a man giving up and gaining peace before his death]]. Hear a woman speaking 'Trois', 'Sept', 'Cinq', 'Six', 'Quatr'? "3,7,5,6,4" in Japanese sounds like 皆殺し, which means [[spoiler: "kill everyone"]]. That crackling noise near the end? It's the sound of an [[spoiler: incinerator, like those you see in a mortuary]].
* TastesLikeDiabetes: Once you reach the apex of a song, your little drum character starts dancing "The Monkey"... and it's absolutely ''adorable''!
* ThatOneAttack: There are so many candidates of this trope that it'd be a pain to write all of them so here are some examples (Might update later on):
** [[https://youtu.be/6n2PvrWjyxg?t=1m56s "Rotter Tarmination"]]'s Ura Oni Chart. That particular part scrolls at 400, then a whopping '''800''' BPM. Before finally ending with an impossible balloon note (You'll need 766 rolls for that)
** [[https://www.youtube.com/watch?v=MVDHw564dC8 "Suuhaa 2000"]] can caught any first-timers off guard. The song itself starts of pretty calm, although if you look at the ''speed'' either Don or Katsu (Depends on which drum you play as; Left for Don and vice versa) is "dancing", you'll see how fast this song actually is. Up to the 301st note, it's pretty easy. The [[https://youtu.be/MVDHw564dC8?t=1m43s madness]] after that will prove that this ain't easy shit. The ''latter half'' of the notes left is '''crammed into a period of 30 seconds or so'''.
