If you want to have the audio start playing immediately for a given song, load that song, bring up the audio player, tap the settings icon (the gears) and enable the "Automatically play audio when song is loaded" setting. If you just want to start audio playback after loading a song, the fastest way to do this is to tap the bottom right corner to bring up the quick action box and then tap on the play icon at the top. Alternatively, you can tap to bring up the overlay then tap on the play icon on the player itself.
