Known for her image reinventions and versatility across the entertainment industry, she is an influential figure in popular music. After signing with Interscope Records in 2007, Gaga achieved global recognition with her debut album, The Fame (2008), and its reissue The Fame Monster (2009). The project scored a string of successful singles, including "Just Dance", "Poker Face", "Bad Romance", "Telephone", and "Alejandro". Her second full-length album, Born This Way (2011), explored electronic rock and techno-pop and sold more than one million copies first-week. Its title track became the fastest-selling song on the iTunes Store, with over one million downloads in less than a week. Following her electronic dance music-influenced third album, Artpop (2013), she pursued jazz on the album Cheek to Cheek (2014) with Tony Bennett, and delved into soft rock on the album Joanne (2016). Gaga also ventured into acting, gaining praise for her leading roles in the miniseries American Horror Story: Hotel (2015–2016) and the films A Star Is Born (2018) and House of Gucci (2021). Her contributions to the A Star Is Born soundtrack, which spawned the chart-topping single "Shallow", made her the first woman to win an Academy, BAFTA, Golden Globe, and Grammy Award in one year. Gaga returned to dance-pop with her album Chromatica (2020), which yielded the number-one single "Rain on Me". She reunited with Bennett for their second and final collaborative album, Love for Sale (2021), and revisited her early pop sound on the album, Mayhem (2025), which contains the chart-topping single "Die with a Smile".
