My Question or Issue

I've followed all the directions for how to upload local files, but when I try to download the playlist on to my phone it says the playlist doesn't have any songs. The songs play on my computer, and then when I click play on other device this box shows up on my phone saying I don't have the song downloaded, as if I was unaware. When I click 'Learn More' it gives me these steps, which don't really make sense.

1. Connect this iPhone to the same WiFi as the computer.

2. Launch Spotify on the computer where the song is stored.

3. Mark the playlist containing this song for Offline Sync on your computer or on this iPhone.

4. Watch as your song magically appears on your iPhone

Trust me, no magic has occurred! What is "offline sync?" I haven't heard of it and can't find any option to mark a playlist as such. If anyone knows how I can listen to my local files on my phone please help.
