spotify on ios and airplay?

Spotify has some strangely labeled buttons, which is why you may not have seen the screen where the airplay option is located. When you start playing a track, or a radio station, you're on what I think of as the main screen. In the top left corner of this screen, where the "back" button usually is for apps on IPhone, there's a button labeled "NP Info Glyph." Clicking this button takes you into a more detailed screen for the track you're playing. If you one-finger-flick to the right through this page, you'll see the artist, track title, album title, and then some options. "Add to" - This button lets you add the track to any playlist in your Spotify library. Star - If you love a song, starring the track adds it to the "starred track playlist" which is a premade Spotify playlist that contains all your favorite songs. Share - You can send the song right to one of your friend's Spotify in-boxes if you think it's one they'd particularly like. Start Radio - Start a new radio station from this track. After all those options is the volume, and finally the "airplay" button. Clicking it takes you to the options for whichever devices you have that are Airplay enabled, and you just choose the device you want, and enjoy from there. If you need to get back to the original screen, somewhere back up near the top of the page is a button labeled "hide." That will take you back to the track's main screen."
