"Do you love listening to Spanish music?"
Duolingo apparently manually codes all accepted sentences rather than making them formulaic — e.g. “subject + verb + object + yes no question” should automatically accept “verb 不 verb” and “verb object 吗”
Note that this is asking for music from Spain, not Spanish language music (that would be 西班牙语音乐).
You could say "Spanish songs" to mean Spanish language... (if it has words it would probably be classified as a song). The only exception I can think of would some spoken literature accompanied by instrumental music - but I'd call those two separate things.
