How do I get songs from Spotify to sync to my iPod Nano?

Just did more research into your question. are these songs that you are downloading onto your computer or are these songs that you are streaming. (playing them without downloading them.) If you are streaming them then there is no way to sync them to your iPod

this is from there website (Here’s how: simply select your Spotify playlist and we’ll transfer the local files in that list directly to your iPod, iPhone or Android device. If your list contains songs you don’t have on your computer, then it’s easy to buy them with a couple of clicks.) so if you don’t have the music on your computer then you have to pay for it. Local files are the ones stored on your computer. so the songs you have on your computer are synced but the ones that you don’t have you will have to pay for to sync to your iPod. (it has very little to do with them making more money and mostly to do with copyright laws. Free music files are illegal music files. if you want the copyrighted files you have to pay for them by law)
