I just created a long playlist of songs using the Spotify desktop app. The songs are local to my PC. I can open the playlist on my phone, but since the songs are not on my phone, I am not able to play it from my phone even though connected to the same wifi network. MORE IMPORTANT: I want to be able to move those songs to my phone and thus have that playlist with me on the go, away from my network. Is there a way to make this sync easily? I hope I don't have to brute force go through the entire playlist, find each local song and then copy that to my phone.
