How do I copy my itunes to my android phone

If you are talking about the subscription service Apple Music (whose forum you are in), you cannot copy any download songs to another device: you have to download them again. You can of course stream them. Anything you download is dependent upon your continuing the subscription. Although suggested by the previous poster, YouTube has nothing whatever to do with this.
