If most of your readers are use the Tapas app to read your stuff, they won't even know you added music as it's not a feature they've added to it. So in that sense.. No.
And then there's people who read on desktop and are able to hear it. A good chunk of them think it might be distracting if the music is too loud or if it doesn't match the scene, or at the very least, they'll wanna choose their own music to read to. So in that instance, probably not.
You should ask what they think of the idea and go from there if you wanna include it
