I've Sound, or simply called I've (アイブ, Aibu^?), is a Japanese techno/trance music production group based in Sapporo, Hokkaidō, Japan. Led by Kazuya Takase, it features the talents of seasoned "sound creators" and many different female vocalists, known as utahime (歌姫^?) to their fans.

They have created the theme songs for many Japanese adult games, most famously the opening "Tori no Uta" to Key's popular adult visual novel and anime Air. More recently, they have been creating the theme songs to anime series. Among anime fans, I've Sound is well known for providing the theme songs to such series as Black Lagoon, the Please! franchise (Please Teacher! and Please Twins!), the Shakugan no Shana series, Starship Operators, Higurashi no Naku Koro ni, the Hayate the Combat Butler series, Nanatsuiro Drops, and Toaru Majutsu no Index.

I've was founded in 1998 by members of the six-member Takase Fight. During this time they produced music for tsushin karaoke and adult game brands based in Hokkaidō. They also made two tracks for the Dancemania series, "If You Were Here" by Jennifer and "Is This The Way You Kill A Love" by Gina, both featured in Dance Dance Revolution.

Adidja Palmer (born 7 January 1976)- better known as Vybz Kartel, is a Jamaican dancehall artist, songwriter and businessman. He has many nicknames, including: Addi, The Teacher, World Boss, Kartel, Vybz, Gaza General and Gaza Don.

Adidja Palmer began his career as a teenager in 1993 with his first recording "Love Fat Woman", released on Alvin Reid's label "One Heart", using the moniker "Adi Banton", a homage to Buju Banton. Palmer was later part of the three-member group "Vybez Cartel", keeping the slightly altered name after group split up, and became a protege of Bounty Killer, for whom he claims to have written nearly 30 songs, including "Gal Clown".

Vybz Kartel rose to prominence in 2003 after a string of hits in Jamaica. The year culminated in a pre-planned on-stage clash with Ninjaman at the annual dancehall festival Sting in Kartel's hometown of Portmore. The clash turned violent when Kartel's crewmembers, as well as Kartel himself, threw punches and assaulted Ninjaman onstage. While Kartel's manager initially blamed Ninjaman for the fracas, Kartel himself quickly apologised to Ninjaman and Sting organizers for the fracas. Four days after the incident, the two artists appeared before the press to announce a settlement of their differences and to end any animosity.

Dee Dee Ramone (born Douglas Glenn Colvin) (September 18, 1951 – June 5, 2002) was an American songwriter and musician, best known as founding member, songwriter, and bassist for punk rock band the Ramones.

Though nearly all of the Ramones' songs were credited equally to all the band members, Dee Dee was the band's most prolific lyricist and songwriter, writing many of the band's most well-known songs, such as "53rd & 3rd", "Commando", "Rockaway Beach", and "Poison Heart". He was initially the band's lead vocalist, though his (then) inability to sing and play bass at the same time resulted in original drummer Joey Ramone taking over the lead vocalist duties. Dee Dee would serve as the band's bassist and songwriter from 1974 through 1989, when he left to pursue a short-lived career in hip hop music under the name Dee Dee King. He soon returned to his punk roots and released three solo albums featuring brand new songs, many of which were later recorded by the Ramones. He toured the world playing his new songs, Ramones songs and some old favorites in small clubs, and continued to write songs for the Ramones until 1996, when the band officially retired.
