How do I sync songs from soundcloud or datpiff
I downloaded the mixtape acid raps by chance the rapper to my computer from datpiff, which is a site that lets you download mixtapes that artists post to it. So I tried to sync it by clicking add files to library, it took me to the file (which had the itunes thumbnail because I selected it to be opened with itunes from the download) so I selected it and opened this but nothing happened. Is this the way I'm even supposed to do this? Thanks for answering.
I'm using windows if that helps, also I plan on putting it on my iPhone 5c so if there's anything I need to know about that, I'd appreciate the help.
iPhone 5c, iOS 8.1.3
