Karol G's latest album, "No Me Arrepiento de Sentir Tanto," has produced an unexpected viral hit in "BbY WOW," a collaboration with Spanish artists Judeline and Risowsky, outpacing streaming growth from the record's higher-profile guest spots with Drake and Bruno Mars. The song's rise highlights how social media momentum, rather than star power alone, can determine which tracks from a major release resonate most with listeners, giving both featured Spanish newcomers their first-ever Billboard chart entries.

Released on 7 August, the album gave Karol G her fifth number one on Billboard's Top Latin Albums chart, with "Ahí" (featuring Drake) topping the Hot Latin Songs chart and "Still" (with Bruno Mars) debuting at number 41 on the Hot 100. However, "BbY WOW" has proven the standout on streaming platforms, opening at number five with 4.5 million US streams and growing a further 28% to over 2.4 million streams in just three days the following week. The upbeat track, built around an interpolation of the Coolie Dance Riddim previously heard in hits by Pitbull and Nina Sky, stands out for its danceable energy against the otherwise heartbreak-themed, sentimental tone of the wider album.
