I would say one of the first two when speaking (the third one sounds awkward with the extra 'for') I would also change the word music to "song" if you keep the article 'a' (I listen to a type of music, but not just a music) "If you like a song, you may hear it over 100 times."

I've got a question if you see my comment and if you don't mind. Can we call a piece of instrumental music a song? I mean to say, not only classical music, but also all kinds of instrumental music. For example, a piece of guitar or harp music or everything else which is just instrumental.

Thank you very much, Paul. As you know, I can't leave comments on your posts. That's why I've got to leave my comment here. And thank you again.

Two things wrong. First, 'music' is uncountable, you cannot say 'a music.' You can say a 'piece of music' or as Diane said, a song. 'A piece of music' could apply to more classical music as well as popular music. You wouldn't describe a piece of classical music as a song. Secondly, 'to listen' is a superior verb choice to 'to hear.' Hearing is passive, listening is active. You seem to be saying that if you like a song or piece of music, you would want to listen to it many times. Therefore, as it is something you are choosing to do, 'listening' is superior. I would also use 'might' rather than 'may' but maybe that is stylistic. If you like a piece of music, you might listen to it over a hundred times. If you like a piece of music, you might listen to it more than a hundred times. The second sentence is most natural.
