Audition Online

Audition Online (Audition, Audi or X-Beat in Japan) is a multiplayer online casual rhythm game produced by T3 Entertainment, a Korean company. The game was originally distributed in North America by Nexon, but in 2009, announced they would not be renewing their license. Since then, the game has been distributed by Red Bana.

The game has multiple modes. Choreography - C - 4 Key is easily the most popular mode, in which players must hit a certain number of arrow keys in the correct order and then press the space bar on beat.

Audition Online's North American release features music from well-known artists such as Lady Gaga, Boys Like Girls, Ke$ha and LMFAO.

Tropes used in Audition Online include:

Alliteration: Several NPC characters, including (but not limited to) Jack Jumpoff, Travis Trounce, Felicia Force, Rachel Raver, Billy Backstep, Sara Steppenice...
And Your Reward Is Clothes: Somewhat averted, as some rooms (as well as licensing matches) require the in game currency, Beats, but otherwise, clothes are the only thing you're earning them for.
Awesomeness Meter: The ranking for timing goes Miss, Bad, Cool, Great and Perfect. Since Perfects are had to achieve and much less common than Greats, they are worth much more points, especially if you can make a combo of them.
- Also played with in Insane mode.
Blind Idiot Translation: Some of the lines in Story Mode look like they were run through Google Translate and then slapped into the game. Some of this has been fixed, but it's still quite noticeable.
The Chosen One: The basic premise behind Story Mode.
Does Not Like Men: Perna/Nana in Story Mode. The narration even describes her as "the despiser of men."
Forced Tutorial: At the beginning.
Just Like Robin Hood: The Masked Dancer in Story Mode. Your character even calls him "Diego Hood" when you first meet.
Magic Dance: Arguably the reason someone could take over/save Audition Town just by dancing.
Purple Eyes: An option in the item shop. NPC's Bobby, Felicia Force, and Perna/Nana all have them, as well.
Trapped in Another World: Your character in Story Mode.
