At the tail-end of 1978, Summer, Moroder and Belotte began working on her seventh studio album, ''[[Bad Girls (Donna Summer album)|Bad Girls]]''. Noting the rise of [[punk rock]] and [[heavy metal music]], the producers and Summer sought to go for a [[rock music|rock]]ier edge on some of the songs while other songs leaned into Summer's R&B roots. [[Harold Faltermeyer]], with whom Moroder had collaborated on the film, ''[[Midnight Express (film)|Midnight Express]]'', was brought in to be the [[arrangement (music)|arranger]] of the album. Released on April 25, 1979, ''Bad Girls'' became an immediate success. The first single, the rock-leaning dance number "[[Hot Stuff (Donna Summer song)|Hot Stuff]]" became Summer's second number one single on the Hot 100, followed by the [[funk rock]]-leaning [[Bad Girls (Donna Summer song)|title track]], the latter of which helped Summer make history as the first female artist of the [[rock and roll|rock era]] to send two songs simultaneously to the top five of the ''Billboard'' Hot 100 and later topped the Hot 100 itself for a five-week run. On June 16, the album became Summer's second number one on the ''Billboard'' 200; on that same date, "Hot Stuff" had returned to number one on the Hot 100.<ref>{{cite magazine |url=http://www.billboard.com/charts/hot-100/1979-06-16 |title=Billboard Hot 100 |magazine=[[Billboard (magazine)|Billboard]] |date=16 June 1979 |issn=0006-2510}}</ref> The album would be Summer's longest-running number one album at six weeks. It also became Summer's first to top the [[Top R&B/Hip-Hop Albums|Top Soul LPs]] chart, with the title track also becoming Summer's first to top the [[Hot R&B/Hip-Hop Songs|Hot Soul Singles]] chart. The album would go on to be certified double-platinum in the United States for sales of over two million copies in the US and sell four million units worldwide.<ref name="ussales">{{cite news |url=https://www.hollywoodreporter.com/gallery/donna-summer-death-career-pictures-326135/4-bad-girls/|title=Donna Summer: The Disco Queen's Life and Career in Pictures|newspaper=[[The Hollywood Reporter]]|date=May 17, 2012|access-date=September 23, 2021|quote=It became the best-selling album of Summer's recording career, selling 4 million copies worldwide, (...)|archive-url=https://web.archive.org/web/20210923045921/https://www.hollywoodreporter.com/gallery/donna-summer-death-career-pictures-326135/4-bad-girls/|archive-date=September 23, 2021|url-status=live}}</ref> At the time, it was the most successful album by a black female artist in history until the releases of [[Tina Turner]]'s ''[[Private Dancer]]'' and [[Whitney Houston]]'s [[Whitney Houston (album)|self-titled debut]] in the [[1980s in music|1980s]].

During promotion of the album, Summer collaborated with [[Barbra Streisand]] on the Paul Jabara composition, "[[No More Tears (Enough is Enough)]]", which was featured on Streisand's ''[[Wet (album)|Wet]]'' album. Around the same time, Summer sought to release "[[Dim All the Lights]]", which was the first sole composition of her career and had hoped she would earn a number one pop single as a songwriter. However, Casablanca Records president Neil Bogart was reportedly more enthusiastic about the release of "No More Tears". Both songs became hits and appeared in the top five of the ''Billboard'' Hot 100 simultaneously, repeating what Summer had done earlier in the year.<ref>{{cite book

And while Summer achieved another historic feat by becoming the first female artist to have three number one singles in a calendar year and having recorded seven consecutive top ten hits by then, Summer was angry that Bogart refused to promote "Dim All the Lights" more, leading to a rift between the artist and Casablanca Records.<ref>{{Cite web|url=http://www.songfacts.com/detail.php?id=26145 |title=Dim All the Lights by Donna Summer Songfacts | access-date=8 September 2021}}</ref><ref>{{cite web|url=http://www.officialcharts.com/search/singles/NO%20MORE%20TEARS%20%28ENOUGH%20IS%20ENOUGH%29/ |title=No More Tears (Enough Is Enough): Official Charts Company |work=Officialcharts.com | access-date=9 September 2021}}</ref> 

''Bad Girls'' resulted in multiple award wins and nominations for Summer. In January 1980, the artist won three more American Music Awards including [[American Music Award for Favorite Pop/Rock Female Artist|Favorite Pop/Rock Female Artist]]. At the [[22nd Annual Grammy Awards|1980 Grammy Awards]], Summer received the first Grammy Award in the category of [[Grammy Award for Best Female Rock Vocal Performance|Best Female Rock Vocal Performance]] for "Hot Stuff", however, she lost the [[Grammy Award for Album of the Year|Album of the Year]] category to [[Billy Joel]]'s ''[[52nd Street (album)|52nd Street]]''. During 1979, Summer played eight sold-out shows at the [[Universal Amphitheater]] in Los Angeles. In October, Casablanca released the first worldwide [[greatest hits]] compilation set, ''[[On the Radio: Greatest Hits Volumes I & II]]''. The album was remixed with each song on the compilation segueing into the next, featuring "No More Tears" and a newer song, "[[On the Radio (Donna Summer song)|On the Radio]]", which was featured in the soundtrack to the film, ''[[Foxes (film)|Foxes]]''. The title track became another top ten hit for Summer, reaching number 5 in early 1980, while the compilation topped the ''Billboard'' 200 on January 5. Like her previous albums, the album would be certified platinum. 

On January 27, 1980, Summer had her own nationally-televised special, ''[[The Donna Summer Special]]'',<ref name=NYT>{{cite news|url=https://www.nytimes.com/tv/show/46047/Donna-Summer-Special/overview|title=The Donna Summer Special|newspaper=[[The New York Times]]}}</ref> which aired on ABC. At this point, Casablanca had wanted Summer to continue releasing singles off the ''Bad Girls'' album but Summer reportedly wanted to venture out of the genre to record her own songs. Following by the receptive failure of "Walk Away" from the ''Bad Girls'' project, Summer sought a new recording deal, later signing with [[David Geffen]]'s recently-formed [[Geffen Records|Geffen]] label. Summer later sued Casablanca for $10 million, leading to a countersuit. Summer would end up settling with Casablanca with rights to her song publishings.<ref>{{cite news|url=https://www.telegraph.co.uk/culture/music/3554408/Donna-Summer-too-hot-to-handle.html |title=Donna Summer: too hot to handle |newspaper=The Telegraph |date=June 13, 2008 |access-date=August 20, 2014}}</ref>
