Question: What is the name of the record label that both Rihanna's albums from 2006 and 2008 were released under?

 It was first released on June 9, 2008 by Def Jam Recordings.  The DVD and Blu-ray release features Rihanna's concert at the Manchester Arena in Manchester, United Kingdom held on December 6, 2007, as part of her Good Girl Gone Bad Tour (2007—2009) which supported singer's third studio album "Good Girl Gone Bad" (2007).  Most of the concert's set list originates from "Good Girl Gone Bad", however, Rihanna also performed songs from her previous albums "Music of the Sun" (2005) and "A Girl like Me" (2006). Good Girl Gone Bad Live is the first live long-form video by Barbadian singer Rihanna.  It also contains a special Documentary Feature that presents Rihanna discussing her experiences during the tour. <SEP>  It was released on April 10, 2006 by Def Jam Recordings.  For the production of the album, Rihanna worked with Evan Rogers, Carl Sturken, StarGate, J. R. Rotem and label-mate Ne-Yo, who wrote the album's second single. A Girl like Me is the second studio album by Barbadian singer Rihanna.  "A Girl like Me" is a pop, reggae and R&B album influenced by Rihanna's Caribbean roots.  The album also incorporates elements of dancehall and rock, as well as ballads, which music critics were ambivalent towards. <SEP> Music of the Sun is the debut studio album by Barbadian singer Rihanna.  It was released on August 30, 2005 in the United States through Def Jam Recordings.  Prior to signing with Def Jam, Rihanna was discovered by record producer Evan Rogers in Barbados, who helped Rihanna record demo tapes to send out to several record labels.  Jay-Z, the former chief executive officer (CEO) and president of Def Jam, was given Rihanna's demo by Jay Brown, his A&R at Def Jam, and invited her to audition for the label after hearing what turned out to be her first single, "Pon de Replay".  She auditioned for Jay-Z and L.A. Reid, the former CEO and president of record label group The Island Def Jam Music Group, and was signed on the spot to prevent her from signing with another record label. <SEP> Key Sounds Label is a Japanese independent record label based in Osaka, Japan, that specializes in trance music.  The label formed in 2001 as a brand of the publishing company VisualArt's and was established to catalog and release music related to visual novels produced by the brand Key, also under VisualArt's.  When Key Sounds Label formed, Jun Maeda, Shinji Orito, and Magome Togoshi were Key's signature composers and have continued to produce the majority of the music on the label, though Togoshi resigned in October 2006 and is no longer affiliated with Key or VisualArt's.  Key and VisualArt's released one single and two remix albums between 1999 and 2000, leading to the formation of Key Sounds Label the following year.  The first official releases on the label were Work-S' debut (and only) studio album "Humanity..." and Lia's debut single "Natsukage / Nostalgia" at the convention Comiket 60 in 2001.  The first release to chart on Japan's Oricon charts was the "Clannad Original Soundtrack" released in 2004.  Between 2006 and 2008, eight more releases—five singles and three albums—also charted on Oricon.  The six singles and two albums released for the anime series "Angel Beats! " charted on Oricon in 2010.
