Night Songs sold several million copies due to a combination of Cinderella's breakthrough single "Nobody's Fool", MTV airplay, and an opening slot on labelmates Bon Jovi's tour, in support of their album Slippery When Wet.
The album peaked at #3 on the US charts on February 7, 1987, and was certified double platinum for shipping 2 million copies there twelve days later. In May 1991, it was certified triple platinum, having shipped 3 million copies.
Leadoff single "Shake Me" failed to chart, but "Nobody's Fool" cracked the Top 20, reaching #13. Third single "Somebody Save Me" went to #66. On May 4, 1987, Cinderella filmed parts of their concert in Philadelphia. These live songs were, along with their three MTV videos, released on home video in August 1987 on Night Songs: The Videos.
On the VH1 program That Metal Show, Night Songs was rated #5 on the show's "top five worst album covers on great albums" list. Eddie Trunk stated that the cover was not that bad, it was just misleading, as it put forward a glam metal image, but the songs inside were classic hard rock and heavy metal. According to some rock/metal critics, Night Songs is considered a heavy metal album. After Night Songs, the band went in a more hard rock/blues rock direction.
In October 2014 for her birthday, guitarist Tom Keifer presented Lzzy Hale of Halestorm with the costume jewelry pin he wore on his right shoulder for the Night Songs album cover. Hale subsequently wore the pin on her right hip on the album cover for Halestorm's 2015 Into the Wild Life, to include a touch of tradition.
