Does anyone think the gamble of releasing La Candida as the next single would pay off? It would, in theory, be a way of fully capitalising on the Mexican market, but a Spanish single would risk completely losing all the remaining fans she has left in France.
Once the album is released, depending on it's early success, several more singles are released. These are popular songs on the album that are sold as a means of promoting the album it is from, which is on sale simultaneously.
