A Video Game / Anime about {{Idol Singer}}s would quite obviously provide plenty of examples of awesome music, but a few of them deserve special mention for their added effect during the scene/event they played out.

-----

* [[http://www.youtube.com/watch?v=YBEUcasMSvU Yakusoku]] - Sung by 765PRO ALLSTARS - Ep 20 of the anime. It's also an AwesomeMoment, HeartwarmingMoment and a TearJerker.
* [[http://www.youtube.com/watch?v=LFjvmiZ84M4 Nemuri Hime]] - Sung by Chihaya ''a cappella'' at first, making the entrance of the orchestra all the more powerful in Ep 21. Another AwesomeMoment because her passion for singing saves the day despite Kuroi's rigging of the background music, and it lets Jupiter realise what he's doing and leave for good.
* Chihaya's original song from the first game, [[http://www.youtube.com/watch?v=lXq_18N3K2Q Aoi Tori]]. It is a beautifully melancholic piece that practically defines Chihaya's feelings. It [[http://www.youtube.com/watch?v=h60kqtbbM6Q returns as an arrange for Episode 4's ending]], complete with a new recording and a beautiful ''a cappella'' performance in the episode itself.
* [[http://www.youtube.com/watch?v=r5O0b02uEmE L.O.B.M]] - Sung by 765PRO ALLSTARS - Ep 10. A ThemeMusicPowerUp.
* [[http://www.youtube.com/watch?v=_kW-hIaOWBc Watashitachi wa Zutto]] [[http://www.youtube.com/watch?v=dGH58mKuhgA ...deshou?]] (previously known as Itsumademo Dokomademo) - Sung by 765PRO ALLSTARS - Ep 25. The HardWorkMontage just added the effect.
* [[http://www.youtube.com/watch?v=14U2Yho1EtQ Marionette no Kokoro]] - Sung by Miki in Episode 13. Doubles as a {{Determinator}} moment for her, since she was already tired from singing/dancing her previous song.
* [[http://www.youtube.com/watch?v=xJl2aNfD2tw Jibun Rest@rt]] - Sung by 765PRO ALLSTARS (without Iori, Ami and Asuza). It's a defining moment in the series, where the idols that aren't Ryuuguu Komachi step up and prove to the world that they're just as talented and that they can stand on their own.
* [[http://www.youtube.com/watch?v=FuVX95dqtyY ALRIGHT*]] - One of Yukiho's image songs, which she sings in episode 3 of the anime as a way of overcoming her own [[DoesNotLikeMen weakness.]]
* [[http://www.youtube.com/watch?v=UFMYHVPaDFo Little Match Girl]] - Shows how Yukiho has become confident in herself, enough to take the lead in the center of the stage with no problems. The [[http://www.youtube.com/watch?v=yK0L0tjAE4E M@STER version]] is even more glorious.
* [[http://www.youtube.com/watch?v=IIDkEad-V8c arcadia]]. It just radiates awesome. Also was used as a theme song for the trailer of [[http://www.youtube.com/watch?v=gF0DON1ExJI Mujin Gattai Kisaragi]] and starts playing when Haruka reveals herself as the BigBad.
* [[http://www.youtube.com/watch?v=cVkNwsYMUzU Agent Yoru o Yuku]] has always been one of the most well-known songs in the series. However, the song really brings out the awesome in Episode 8, [[http://www.youtube.com/watch?v=vzBAo72t938 where it plays in the background while Makoto has an epic kung-fu fight with a grunt on top of a ladder bridge.]]
* The last episode's performance of a mashup of the two openings, [[http://www.youtube.com/watch?v=yk-AfQqB9gw READY!!&CHANGE!!!!]], in its fully animated glory. All the girls manage to hold this concert together even with their incredibly busy schedules.
* [[http://www.youtube.com/watch?v=QUExDidUick ALIVE]], the personal song of DS idol Hidaka Ai, a massive {{genki girl}} trying to make it as an Idol by her own merits, instead of just riding the coattails of her famous mother (as many producers have advised). Ai auditions and always gives her all, but gets rejected and fails more often than not; keeping up the cheerful persona to others, but secretly crying about it alone at a park at night. Knowing this, the song becomes that much more of a Tearjerker and serves as an inspiring theme for perseverance in general.
* [[http://www.youtube.com/watch?v=DlPve1EHxIg Overmaster]] is Project Fairy's badass rock ImageSong, which exemplifies the idea that AllGirlsWantBadBoys. Made even better when [[BewareTheNiceONes sweet and shy Yukiho covers it]].
* [[TitleDrop THE iDOLM@STER]] is a catchy and inspiring song that pretty much represents what iM@S stands for. Its incarnation in the [[{{VideoGame/TheIdolmaster2}} second game]] is [[http://www.youtube.com/watch?v=8I58aC1RGCs THE iDOLM@STER 2nd-mix]], a techno remix which somehow makes it even better.
* Shiny Festa gives us [[http://www.youtube.com/watch?v=lzrIp3vtzfg edeN]], quite possibly one of the most awesome rock songs in the series.
* [[http://www.youtube.com/watch?v=czXTa1vu48k DREAM]] is an incredibly cool song, enough that it got its [[http://www.youtube.com/watch?v=yKrCAdcLKHc own dance]] in One For All.
* It's time to party with [[http://www.youtube.com/watch?v=8hMAh0c50Gg Machiuke Prince]]!
* 961 Jupiter's [[http://www.youtube.com/watch?v=7_3SzYyC0tM Alice or Guilty]] is fairly awesome in itself, rivalling 961 Project Fairy's Overmaster in coolness.
* [[http://www.youtube.com/watch?v=1N3VkLo2Rz8 Tonari ni...]] is incredibly emotional, and the heartbreaking lyrics strongly imply that the singer is left behind by a person who passed away. The [[http://www.youtube.com/watch?v=eSoaMp2iN9U "movie"]] in the anime shows it as such, with Azusa whispering "I've decided to marry." at the hill mentoned in the song as she decides to move on. It's something you normally wouldn't expect from an idol series.
* [[http://www.youtube.com/watch?v=cvId5JelbOw relations]] is one of the series' earliest rock-type songs.
* Chihaya's [[http://www.youtube.com/watch?v=-EjE6U5LeTg Me ga Au Toki]] manages to be fast paced and emotional at the same time.
* Makoto's image song [[http://www.youtube.com/watch?v=ZR5zTPolS_w Meisou Mind]], which is incredibly cool.
