WHY ENGLISH LYRICS TO FOREIGN SONGS?

I don't like translations of songs; they seldom sound right. Songs were meant to be sung in the language they were written in. With foreign, non-English speaking artists this always happens: a mediocre (in my opinion) version is sung on the radio because it's assumed no one in this country wants to hear anything other than English. I'm starting to learn Spanish now....maybe listen to Latin stations?
