Sequential play:
You are correct. Each song must be initiated separately. For continuous play, you need to make a pre-recorded playback track. for hands-free start/stop and page-turn forward/back consider Air-Turn. You still have to allow time for the player to compose the track each time.

The player (and key) settings can be adjusted and retained separately for a song in the master song index as well as copies in different playlists.
