Their debut song "10 Out of 10" was one of the breakthroughs in the Korean Pop Music industry because of the incorporation of acrobatics, something that only backup dancers for idols used to do.
"Again & Again" won a triple crown, consisting of the KBS Music Festival 2009 Song of the Year and the titles of "Best Male Group" and "Artist of the Year".
Despite mixed reactions towards "Heartbeat", the song cemented the group's image as beastly idols with powerful stunts and shirt-ripping. Each performance, whether it be a live show, a concert, or a simple stage, also featured a different ending to the song, with some of the endings created only during the performance itself.
"Don't Stop Can't Stop" is about the group never giving up even though they face many hardships and haters trying to pull them down.
"Without U" starts off melancholic, but later features a rougher and stronger sound.
"I'll Be Back" is one of the songs that the group found to be the hardest due to its difficult dance moves.
Even though "Hands Up" was banned in some shows because it referenced "drinking" in the lyrics, it was a sensation not just in Korea and Japan but also worldwide, because of its catchy verses, rhymes, hook, rap... actually everything about the song is catchy.
Despite the belief that the GROWN album was not successful in terms of sales, "A.D.T.O.Y." was popular enough, with people from different fandoms wishing that their biases would also perform songs with an "adtoy concept".
"Beautiful" and "Come Back When You Hear This Song" have both the ballad and dance feel mixed together. "Beautiful" later got a ballad version which was performed during a concert, while "Come Back When You Hear This Song" was rearranged by JYP, giving it a ballad-like intro, which was used during the JYP Nation tour in 2014.
In an interview, the host says that if she didn't know that "Back to Square One" was just a song in the album, she would have mistaken it for the title track.
Listening to "Winter Games" really makes the listener feel the cold, winter atmosphere. The lyrics and melody provide the song with a fairytale-like nature.
Jun. K's "NO LOVE" gradually builds up - the intro is slow, the verses are ballad-like, but the chorus is the climax. The mixture of different genres and singing styles highlight Jun. K's vocals. The other members have also covered the song, and they do not fail to meet the expectations.
Jun. K wrote two Korean title tracks:
"Go Crazy!" is a disco and house song with retro elements about partying all night long. JYP admits that he can't make a song better than that for the album.
"My House" is a dance song with house and slight swing elements added to it. If you listen closely, the base for the instrumental is just simple guitar chords.
Junho's "Nobody Else" gives off a slow and sensual vibe despite being mostly rapping.
"Hallucination" is a song loved by both fans and members themselves, and is usually described as something that sounds like a track from a Korean Drama soundtrack with the dreamy atmosphere that the song provides.
"Your Man", Jun. K's composition, is definitely a runner-up to the title track with the use of electric guitar and synth sounds. The song provides a sexy playboy image.
Jun. K's solo song "THINK ABOUT YOU" is a ballad with rapping, dubstep, and use of future bass, giving the song quite the modern feel.
Overall, the songs in the album GENTLEMEN'S GAME seem to have a theme, as all of the songs complement each other but are not the same genres.
"Promise", written by Taecyeon, features piano and future bass and has a slower pace than usual title tracks. Most of the song's reviews mention the lack of the familar JYP style.
Written by Wooyoung, "Giv u Class." is a slow song that features a trap style. "Without Trying", also by Wooyoung, is a mix of trap and R&B.
"Make Love", as stated in an article, is "smooth like butter and feels like water as it flows cleanly through your body and into your soul". The song was written by Chansung.
