What are some examples of soft AC songs that test well with Hispanic audiences? Are we talking about stuff like Gloria Estefan's "Rhythm Is Gonna Get You" and "Conga" that would be considered too uptempo and "ethnic" for a soft format -- even though they were across-the-board hits at CHR as currents? Ballads by Hispanic or African-American acts? Specifics, please.
No, we are not talking about Hispanic artists. We are talking about songs from the US charts that were also big hits in different areas of Latin America.
As an example from an earlier decade, in Latin America CCR sold more records than the Beatles.
Look at the WFEZ playlist and you will see songs that appeal to both Hispanics and non-Hispanic white segments of the Miami population.
Also keep in mind that the US songs that were hits in the Caribbean Basin (PR, Cuba, DR, Colombia, Venezuela, Nicaragua plus Ecuador) where most Hispanics in Miami have their heritage are often not exactly the same as those favored by persons of Mexican heritage in the same demos.
