Questions & Answers about Вечером мне хочется тишины, а не громкой музыки.
Вечером is the instrumental case of вечер used adverbially to mean in the evening / in the evenings (as a time of day).
В вечер normally needs extra specification (e.g., в этот вечер = that evening, в тот вечер), and it sounds like you mean a particular evening event/time, not just the general time period.
Мне is dative and marks the person who experiences the feeling/desire. With хочется, Russian often uses an impersonal construction: to me it feels like / I feel like.
So мне хочется ... is literally to me it is wanted ... → natural English: I feel like / I want ....
Я хочу = a direct, deliberate want (I want), more “agentive.”
Мне хочется = a more spontaneous, mood-based desire (I feel like, I’m in the mood for). It’s very common when talking about cravings, atmosphere, comfort, etc.—like wanting quiet.
