Boruch Dayan HaEmes. I am so sorry for your loss. Your best move is of course to ask your LOR, but before you reach him, the laws of aveilus apply only after the kevurah. Until then, your thoughts are to be occupied with making plans for the levaya. So no brochos or davening, etc. You may shower before the levaya, and don’t change your shoes to non-leather until after the kevurah. As to music, ask the rov, but perhaps you can find something else equally soothing (like a sound machine or a fan) that can lull you to sleep. I did not listen to music for the year and a half (my parents’ deaths overlapped)of my aveilus. For someone whose PARNASSAH is music, there are exceptions.
