99.9F° (Ninety-Nine Point Nine Fahrenheit Degrees) is the fourth album by the American singer/songwriter Suzanne Vega. Released in 1992, the album marked a significant departure for Vega, as she embraced a more electronic-influenced, experimental sound. It peaked at #86 on Billboard Magazine album charts, as well as two songs to their Modern Rock charts, including "Blood Makes Noise," written with Kevin 'Doc' Sullivan of Skinny Puppy and Nine Inch Nails, which reached #1. The album was also Vega's fourth Top 20 album in the UK. Despite its low chart position in the US, the album was certified gold by RIAA in October 1997, which marks 500,000 copies sold. It also reached silver status in the UK by the BPI in March 1993. The LP remains out of print in US. 　　It was the first of two of Vega's albums to be produced by Mitchell Froom, whom she later married.
