Copy local playlist from computer and then play on my iPad without the files?

If I have all my mp3 on my computer, make a playlist of them in spotify, could I then log in on my Spotify on my iPad and then play the songs without having to have the mp3's on the iPad or choose "Play offline"? Like, can Spotify on my iPad track down the songs in the Spotify library and then play it just by the aritst/title/album? Or do I have to sync the songs in "offline mode"?
