Cell phones are a must in case you have an emergency or something. Listening to music is a no no in my book.
Ditto. You're out there to become one with nature and allow yourself to disappear into the woods. If the music is that important or you get bored, then hunting may not be for you. You need to be able to hear the deer walking on crunchy leaves, the squirrels chittering that says something is near, and so forth.
