Hey @orville, I first heard the song when I was returning to visit Mexico. I've heard a number of artists cover the song. Here's something about the song on wikipedia:
"¿A quién le importa?" (English: literally, "To whom does it matter?"; idiomatically, "Who cares?") is a successful single released from the Spanish pop rock band Alaska y Dinarama's 1986 No es pecado album. Fangoria – composed of two of the song's three original artists, Alaska and Nacho Canut – recorded an updated, more electronic version of the song along with a new music video. The song was featured in the "Astracanada" disc of the album. Other cover versions include those by Pink Punk and Christina Rapado.
BTW, I'm going to have to check out "La Casa de las Flores" during this SIP...
