Any way to download music online without having two song copies?

Depends if you have a mac or a pc really, but if you want you could start illegally torrenting, which is what i do btw so its kewl. All you do is go download a program like utorrent or vuze, then go to a website like demonoid or thepiratebay.org and download whatever album u wish, then open it with either one of the programs you downloaded. It will then start downloading and when its finished you'll have one copy of each file on the album to do with what u please. There u go, i hope this helps, and if you have any more questions email me or something. :]
