Translation:Until today, I do not like classical music.
This sentence suffers from lack of context (but that is par for the course here).
Does the person still not like classical music?
"To this day, I don't like classical music."
(because "gosto" is present tense, I think maybe this is the best answer)
Did they change their opinion after something happened today?
"Until today, I didn't like classical music."
(But wouldn't this need "gostei" for this meaning?)
The word bank in the mobile app still (6/4/19) only offers "until today I do not like classical music" as the English answer.
The only context in which this would make sense is if I haven't ever liked classical music, still don't now, AND will like it at some point later today, AND know this already now.
Obviously this is not what the PT means, so the default EN needs changing.
