Słuchać requires Genitive
Słuchać zenona martyniuka
Why is "Słuchasz muzyki." not accepted? Is there a rule when you have to add the personal pronoun ("ty" in this case)?
I guess if you say "do muzyki" it's incorrect?
Yes, it's incorrect.
Why "Czy sluchacie muzyki" doesn't count?
Czy is an interrogative particle, but this sentence is not a question.
