[8][9] She was regarded as a diva since she surpassed Sarah Vaughan and won the 1948 Miami Jazz Festival, with the song "For You" that was composed by their family friend Arif Mardin, the 12-time Grammy Award winning Turkish-American music producer.
However, she has a half-brother Süleyman Şefik Söylemezoğlu named after their paternal grandfather, who is the son of Aynur Bıyıktay-Söylemezoğlu (the daughter of Ömer Halis Bıyıktay and the niece of Kâzım Karabekir, from her mother's side).
Şehrazat was also the producer of superstar Ajda Pekkan, Sibel Tüzün, the former Eurovision Song Contest participant, Yıldız Kaplan, Reyhan Karaca, Zeliha Sunal, and Band AF.
[16][17][18][19] Sezen Aksu, another Turkish pop music singer, songwriter and producer who sold over 40 million albums worldwide, is the closest colleague of Şehrazat.
On 2 February 1985, Şehrazat as a special guest star performed in the music feast of a monthly TV-show "Do-Re-Mi", called "Jazz and Dance Night", with the song "Break Me".
She concurrently appeared in Cem Özer's Star TV show "Laf Lafı Açıyor" on 19 June 1992 and on 3 May 1996 when the show transferred to Kanal D. On 24 January 2004, Şehrazat celebrated her 30-year anniversary as a lyricist and composer, which took place in the form of a huge concert named "Şehrazat Şarkıları" and given in Istanbul at the Levent İş Sanat Cultural Center in association with Türkiye İş Bankası.
She sang some of her greatest hits and had guests such as Sezen Aksu, Nilüfer, Ajda Pekkan, Aşkın Nur Yengi, Emel Müftüoğlu, and Muazzez Abacı join her on stage.
[20][21] At the instance of Şehrazat, all proceeds from this concert as well as profits from the sales of each ticket sold for the event was donated to the TSK Elele Foundation of the General Staff of the Republic of Turkey.
