Karol G, Judeline and rusowsky’s “BbY WOW” remains at No. 1 on Spain’s LOS40 chart for a second consecutive week, according to the chart broadcaster’s October 10, 2026 report. The current ranking is a concrete measure of audience-facing chart traction, distinct from social-media claims that a song is simply viral.
What does the October 10 LOS40 chart show?
LOS40 reports that the collaboration retains the top position for a second week after initially entering the ranking at No. 15. The chart’s reporting also describes international chart activity, although those separate rankings should be checked against their individual dated official editions before quoting exact cross-platform positions.
Why this collaboration matters
The track links a globally established Latin artist with two Spanish alternative performers. For Judeline and rusowsky, exposure alongside Karol G can introduce their individual catalogues to listeners beyond existing audiences. The chart performance gives music editors a reason to examine the collaboration’s reach, rather than relying on speculative stream figures.
What to watch after the second No. 1 week
Sustained chart positioning over multiple editions, new music from the collaborators and the track’s official music-video activity can help explain its ongoing campaign. Any exact streaming or video totals should be attached to a platform and measurement date; none are invented here.
