Question: Who has written more books, Tina Turner or Shirley Manson?
Context: Tina Turns the Country On!  is the debut album by Tina Turner, released in 1974 on the United Artists label in the U.S.  The album was recorded while Turner still was a member of the Ike & Tina Turner Revue. Tina Turner (born Anna Mae Bullock; November 26, 1939), is an American-born Swiss recording singer, songwriter, dancer, actress, and author.  Born and raised in the Southeastern United States, Turner relinquished her American citizenship after obtaining Swiss citizenship in 2013. "A Fool in Love" is the debut single for the team of Ike & Tina Turner.  Originally written by Ike Turner, the song became the first official single featuring Tina Turner and was the duo's first hit single, released on the Sue Records label in 1960. Acid Queen is Tina Turner's second solo album, released in 1975 on the EMI label in the UK, and on United Artists in the US.  Although it is a Tina Turner solo album, the very first single, "Baby Get It On", was a duet with Ike Turner, Tina Turner's musical partner and husband at the time.  As it turned out, it was her last solo album to be released before she left Ike Turner and the Ike & Tina Turner Revue. It's Gonna Work Out Fine is the fourth studio album released by Ike & Tina Turner on the Sue Records label and the fifth associated Ike & Tina project (including the instrumental album, "Dance with Ike & Tina Turner & The Kings of Rhythm") released altogether during their Sue Records tenure.  It's notable for their title track, also released on the "Dynamite! " album.  The Turners left Sue Records in 1964 in search of better deals.  The album also features Tina Turner's first lyrical composition, "Tinaroo".  The cover of the album features a young Tina Turner solely on the cover without her partner. Workin' Together is a 1971 album recorded and released by Ike & Tina Turner on the Liberty Records label.  Their second album with the label, it was also their most successful album to date.  Much like their previous album, "Come Together", the album featured several covers of rock songs and also featured renewed versions of previous Ike & Tina songs, which was a habit for the couple.  The album featured the duo's biggest-selling hit, a funk rock styled cover of "Proud Mary" and also featured another popular Ike & Tina song, the Ike Turner & Alliene Bullock-composed "Funkier Than a Mosquita's Tweeter", later covered by Nina Simone.  Several of the songs were written by Ike (including one by "Eki Renrut", which is Ike Turner's name backwards) and "The Way You Love Me" which was a song the Turners had recorded for their very first studio album together, "The Soul of Ike & Tina Turner", a decade earlier. "What You Get Is What You See" is a song by recording artist Tina Turner from her album "Break Every Rule" (1986).  The song was written by the Terry Britten and Graham Lyle team and was notably different from the three previous singles that they had written for Turner, "What's Love Got to Do with It", "We Don't Need Another Hero" and "Two People", as it was an up-tempo country-tinged rock track featuring Eric Clapton on guitars.  Tina Turner said in an interview that "What You Get Is What You See" is her favorite song from the album. Shirley Ann Manson (born 26 August 1966) is a Scottish singer, songwriter and actress.  She is the lead vocalist of the alternative rock band Garbage.  For much of her international career Manson commuted between her home city of Edinburgh and the United States to record with Garbage; she now lives and works in Los Angeles.  Manson gained media attention for her forthright style, rebellious attitude and distinctive voice. "Better Be Good to Me" is a hit rock song, written by Mike Chapman, Nicky Chinn and Holly Knight, featured on Tina Turner's fifth studio album, "Private Dancer" (1984).  The song was originally recorded and released in 1981 by Spider, a band from New York City with co-writer Holly Knight as a member.  Tina Turner's version was successful in the United States on the Hot 100 and the US R&B/Hip-Hop chart.  It peaked at number five on the "Billboard" Hot 100 and number six on the US R&B/Hip-hop chart.  At the 27th Grammy Awards in 1985, it won Best Rock Vocal Performance, Female, one of four Grammys awarded to Turner in that ceremony. "It's Only Love" is a song by Canadian singer and songwriter Bryan Adams, featuring American singer Tina Turner.  It was the sixth and final single from Adams' album "Reckless" (1984) and was included on Tina Turner's live album "Tina Live in Europe" (1988), as well as being added to both artists' greatest hits compilations: Adams' "Anthology" (2005) and Turner's "All the Best" (2004).  It reached number 15 in January 1986 on the "Billboard" Hot 100 in the U.S. and number 29 in the UK.  The 12" single included the 1985 live version that would later appear on the 1988 album "Tina Live in Europe".
