That is not a good question. You set up a scenario where music is to be expected and then ask, if people would play/try it. They would. You do not hear the music or lack thereof on the advertisement page. But they might not like the game as much as they might have, if it would have had good music.
What you really should ask, if people would enjoy it more or less, based on having music or not. And if you have a genre where such sounds are the expected thing, of course, music is a must. People that do not like it, can turn it off. Other people would see it as unfinished. Might as well use stock assets for your hero or the bosses.
Know your audience. And in that genre, well, the music can have a huge impact.
In other genres, you can even get away with having no sound at all.
