From the little I've read about Re:Zero from the summary I checked, it really didn't seem like something I would want to read, so I honestly can't give my opinion about how effectively they pull it off.

Whether or not the piece of writing could or couldn't give off a good atmosphere isn't so much the problem here, but more that I have a very specific atmosphere or feeling that I get while writing a certain scene and the piece of music does help facilitate that atmosphere. I sometimes wonder if the people reading my work will actually be able to get that same feeling without any music.
