How Do I Find Any New Merengue, Salsa, And Bachata Songs?

If you know any radio, or club DJ that have Music Labels connections, that would be great for you.
Other way, you’ll be stuck with Radio Listening–which sometimes tells you they’re playing the newest hit from somebody, which is not true because you already have that somebody’s CD and have know that hit from sometime ago.
You can ask friends with similar interests as yours to exchange music with you too.
Good Luck!
