When I download a file, say an mp3 file, I ALWAYS change it to fit my needs. I do not have an "ear" for music and can not tell the difference between 64 and 128 kbs. I am sure some people can, but it sound exactly the same to me. So, if it sounds the same, why take up the HD space when not necessary for my enjoyment. AND I most always change the tags to fit my needs also. A lot of times after importing it into my mp3 player the song title, album or something is not correct so I change it.
If I downloaded a file from you, you would not find that song from me looking the same
