[14] Park revealed a short preview of "I Got Your Back" on Twitter with Jeon Goon, the songwriter and producer of Taeyang's "I Need A Girl" and Wheesung's "Fading Star" (Korean: 별이 지다; Revised Romanization: Byeori Jida) on November 30, 2011.

[15] Park confirmed at many times via Twitter many collaborations with top hip hop Korean artists, including Dok2, The Quiett, Dynamic Duo,[16][17] Bizzy[18][19] and legend Korean hip hop artists Tiger JK & wife Tasha Reid.

[26][27] Park stated that they were around "4 or 5" tracks that he either "threw away or gave to someone else", and that due to announcing a release schedule ahead of time, he felt rushed and pressured to add the finishing touches to the album.

Written and composed by Park, it's an R&B song with a sweet melody and lyrics about a man confessing his love for a woman.

[33] Park continued to work with fellow AOM crew mate Cha Cha Malone for 4 tracks in this album : "Up And Down", "Go", "Come On Over" (Korean: 놀러와; Revised Romanization: Nolleowa) and "Turn Off The Phone" (Korean: 전화기를 꺼놔; Revised Romanization: Jeonhwagireur Kkeonwa).

The album also includes Malone's previous track with Park from his first mini-album, "I Can't Be Without You" (Korean: 너 없이 안돼; Revised Romanization: Neo Eopsi Andwae), in acoustic version, with the guitar played by Johan.

Park worked with famous US producer Rob Knox and James Fauntleroy from the Y's for the track "I Love You", featuring Dynamic Duo.

It is described by music critic Noh Jun Young as "a trendy and groovy song with a good balance of a K-pop and American melody".

[35] "Star" (Korean: 별; Revised Romanization: Byeol), the title track of the first part, was written and composed by Jeon Goon.

[37] New Breed also includes hip hop songs, with "AOM & 1llionaire", "Enjoy The Show", "Wasted" (Korean: 훅 갔어; Revised Romanization: Hug Gasseo) and "Clap".

"Enjoy The Show" is described by music critic Noh Jun Young as a "macho, energetic hip-hop" song.

The concept of the album cover, chosen by Park himself, was inspired by the tattoos of Canadian artist and fashion model Rick Genest a.k.a.

[40][41][42] The cover features a portrait of Park in a black suit and heavy chains with half part of his face looking like a zombie, described as a Mexican "Day of the Dead" skull.

The video also pays homage for the 1980 French movie La Boum, re-enacting the iconic headphones scene.

The choreographers for the music video of "Know Your Name" are Andrew Baterina, Jackie Launtchang (both from SoReal Cru) and Haw (from Prepix).

Dok2 then starts to rap, and as soon as he finishes his part, Park is seen dancing with Andrew Baterina (SoReal Cru) and Daniel Jerome (AOM).

He then calls a female waitress, played by Park Se-young, to order a drink, and immediately falls for her at first sight.

This music video is featured around Park's iconic album cover, with make-up inspired by Rick Genest (Zombie Boy).

Park also includes a snippet of him singing his mellow, acoustic track, "I Can't Be Without You", causing laughs around the studio.
