\n\tWelcome to Billboard Pro\u2019s\u00a0Trending Up<\/a>\u00a0newsletter, where we take a closer look at the songs, artists, curiosities and trends that have caught the music industry\u2019s attention. Some have come out of nowhere, others have taken months to catch on, and all of them could become ubiquitous in the blink of a TikTok clip.<\/em><\/p>\n \t\t\t\t\tExplore\t\t<\/p>\n<\/h3>\n \t\t\t\t\t\t<\/p><\/div>\n \t\t\t<\/a>\n\t<\/div>\n <\/p>\n \t<\/span><\/p><\/div>\n<\/div><\/div>\n See latest videos, charts and news<\/p>\n<\/p><\/div>\n \n\tThis week: Ace Frehley\u2019s death sends fans to his solo and KISS catalogs, Karol G\u2019s sexy soundtrack becomes a new viral hit and an unkillable \u201990s karaoke staple still has it goin\u2019 on.<\/em><\/p>\n \n\tThe rock world was shaken by the sad news<\/a> last Thursday (Oct. 16) that Ace Frehley, lead guitarist and occasional singer for rock legends KISS<\/a>, had died at age 74 \u2014 following a brain bleed, which came as a result of a fall in his home studio, and led to him being put on (and ultimately taken off) life support. The Rock and Roll Hall of Famer, also known as \u201cThe Spaceman\u201d or \u201cSpace Ace,\u201d was considered one of the greatest guitarists of his generation, and one of the great six-string showmen of all time. <\/p>\n \n\tFollowing his death, there was an outpouring of grief and love<\/a> for Frehley,\u00a0and a surge of renewed streaming interest. In the three days after Frehley\u2019s passing (Oct. 17-19), the KISS back catalog racked up nearly 6.8 official on-demand U.S. streams \u2014 a gain of 187% from the three-day period before it (Oct. 13-15), according to Luminate \u2014\u00a0while also selling nearly 4,500 digital songs, a 1,664% rise from the previous period. <\/p>\n \n\tUnsurprisingly, the biggest of those song gains came courtesy of the 1978 Billboard Hot 100<\/a> No. 13 hit \u201cNew York Groove.\u201d (Though credited on the chart to Frehley solo, the song is credited to the full KISS in Luminate \u2014 as its self-titled parent album was technically a band release, with all four of the group\u2019s members famously releasing solo efforts under the KISS umbrella on the same day.) \u201cGroove\u201d amassed 318,000 streams and sold over 700 copies over that period, gains of 530% and 4,217%, respectively. <\/p>\n \n\tAnd while apart from \u201cGroove,\u201d Frehley never had a tremendously prolific solo chart profile, fans also headed back to his solo stuff after his passing. The guitar great\u2019s solo catalog collected 586,000 streams and nearly 800 songs sold over that period, gains of 2,940% and 5,140%, respectively. \u2014 ANDREW UNTERBERGER<\/em><\/p>\n \n\tKarol G<\/a> got her wings at the 2025 Victoria\u2019s Secret Fashion Show, and so did \u201cIvonny Bonita,\u201d a song from her Tropicoqueta <\/em>album.\u00a0<\/p>\n \n\tThe Latin superstar performed the opening track from her latest LP, released in June, at the Oct. 15 show, and her sultry performance quickly gained traction across social media. The song had already been a popular sound<\/a> on TikTok amongst the edit community<\/a>, but the VSFS performance kicked its streaming increases into high gear. Across the first four days of last tracking week (Oct. 10-13), preceding the fashion show, \u201cIvonny Bonita\u201d earned over 366,000 official on-demand U.S. streams, according to Luminate. Across the first four days of this tracking week (Oct. 17-20) following the fashion show, the track jumped over 204% in streaming activity to 1.11 million official streams. The official YouTube upload<\/a> of Karol\u2019s performance has earned over 1.1 million hits in four days.\u00a0<\/p>\n \n\tNotably, Karol G is also the leading female nominee at the 2025 Billboard Latin Music Awards<\/a> (10), which will air live via Telemundo on Oct. 23 at 8 p.m. ET from Miami, Fla., coinciding with Latin Music Week. \u2014 KYLE DENIS<\/em><\/p>\n \n\tAs anyone who\u2019s spent enough time around a jukebox or karaoke machine knows, there are few \u201990s hits more undying than 4 Non Blondes<\/a>\u2018 1992 alt-rock power ballad \u201cWhat\u2019s Up?\u201d The song, a No. 14 Hot 100 hit in 1993, has delighted and tormented pop and rock fans in nearly equal measure for over 30 years now \u2014 and in 2025, the song seems to somehow have just as much cultural currency as ever. <\/p>\n \n\tIn September, \u201cWhat\u2019s Up?\u201d was heavily interpolated by guest singer Lizzo for the hook and quasi-bridge to Cardi B\u2019s Am I the Drama?<\/em> song \u201cWhat\u2019s Goin On\u201d \u2014\u00a0the title, of course, that people have been incorrectly (albeit understandably) calling the original for the entire time it\u2019s been popular. Then, in recent weeks, the song has exploded on TikTok<\/a> as part of a mashup with Nicki Minaj\u2019s \u201cBeez in the Trap,\u201d going so viral that SNL<\/em> cast member Marcello Hernandez and recent host and musical guest Sabrina Carpenter even filmed a short promotional video<\/a> to it before last Saturday\u2019s episode. <\/p>\n \n\tAll this has resulted in the song \u2014 which already regularly pulls over two million official on-demand U.S. streams a week \u2014\u00a0rising even further in recent weeks. Last tracking week (Oct. 10-16), it garnered 2.6 million streams, a gain of 11% from the week before. And this tracking week, it\u2019s gotten off to an even hotter start, racking up 901,000 streams across its first two days (Oct. 17-18), up 20% from the same period last week. \u2013 AU<\/em><\/p>\n\n
