Whether it is HD music or "normal" definition, the question of compression remains. The advantage is that the weight of the songs is reduced, so they take up less space in the memory of a phone or a portable music player. With standard MP3 compression, a music album ranges from 500 MB to 45 MB.https://1.bp.blogspot.com/-IXFVzl5J0pU/UINcpZdjp2I/AAAAAAAACSA/SpOz0nelwiM/s1600/a.jpg
