You can load them into iTunes if that’s your thing. I personally don’t like the UI, and have used foobar2000 for a good while (with a custom theme). You can load music onto it using iTunes, or from the files app on your phone. In foobar2000 you can also download from a upnp server, which is nice if you don’t have iTunes (like me). If you have Plex, the Plexamp mobile app works pretty well. It supports your playlists, downloading, and a pretty good radio.
