MIAMI--When Jon Secada's debut SBK single "Just Another Day" first entered the top 10 of Billboard's Hot 100 July 18, its Spanish-language equivalent, "Otro Dia Mas Sin Verte," already had been perched atop the Hot Latin Tracks survey for three weeks.

The group's eponymous label premiere on SBK--slated to be released Tuesday (6)--contains "Muy Suavamente," plus two other Spanish-language tracks.
