'''乐动时代'''[[note]]Put into Google Translate, it comes out as "Music Activity Times". It says "Music Times" on the logo, so let's just call it that for convenience. Analysing the game's files reveals that the names "YDSD" and "Beatmaster" appear a lot in the coding, so you could call it either of those too.[[/note]] is a [[UsefulNotes/{{China}} Chinese]] RhythmGame for iOS by [=RedAtoms=], Inc. It's actually very approachable by non-Chinese speakers (although you may find it hard to find the music in the game elsewhere). It's actually the third in a series, but this article will concentrate on the most recent version.

In terms of gameplay, it has four target zones, to which gems will fall and you have to hit as accurately as possible. The average accuracy of the hits is displayed at the end as a percentage and, of course, [[GameplayGrading graded]].

Songs range in difficulty from 1 to 10 [[HarderThanHard or higher]]. Unlike most {{Rhythm Game}}s, there is only one difficulty level per song. However, some songs do have separate "EZ"[[note]]easy[[/note]], "NM"[[note]]normal[[/note]] and "HD"[[note]]hard[[/note]] versions.

Being a mobile-device game, it has social media implements and downloadable extras.

!!Tropes in the games include:

* AndYourRewardIsClothes: The only reward for [[{{Microtransactions}} spending real money]].
* BossInMookClothing: Those who [[TooDumbToLive don't pay attention to the difficulty level 10]] will get this from "Honey". What is basically Chinese bubblegum pop turns out to be ludicrously difficult.
* CrossOver: [=RedAtoms=] also produce VideoGame/DJMax Ray in China, so naturally, some of the songs from [=DJMax=] make an appearance in the game. Most of them are ThatOneBoss territory.
* EarnYourFun: Most Level 2 songs are unlocked by becoming level 2 yourself, likewise the level 3 songs and so on up to eleven (or, more accurately, 10+)
* GameplayGrading: From F (less than 50% accuracy, which is probably [[EpicFail impossible to do even deliberately]]) to [[RankInflation S]] (over 99% accuracy).
* HarderThanHard: On a scale of 1-10, some songs have the difficulty level 10+
* MadeOfExplodium: All of the gems make a column of pyro matching their colour.
* {{Microtransactions}}: Averted in the case of songs, almost uniquely among {{Rhythm Game}}s (none of the songs have to be paid for) but also played straight (clothes can be bought with diamonds, which cost real money).
* NintendoHard: The level 10 and 10+ songs.
* RankInflation: The S rank makes an appearance.
* RecurringElement: "Ievan Polkka" and "Beethoven Virus" appeared in some form in both of the game's predecessors.
* SequentialBoss: Quest mode's end-of-world battles force you to play two songs in a row against the AI. These songs range from levels 8 to 10+, meaning you are going to face a real challenge.
