How to get songs from Offliberty onto iPhone 6?

On my iPhone 6, I do the routine of copy and pasting the link onto Offliberty, press "Off", it offliberates the link and now it says to right click and save. The problem is, how do I get that Offliberty file into my music app (the red one that comes by default with your phone)?

Edit: do this without doing the same process on the computer, and then syncing through iTunes onto phone.
