SoundHound's music player allows you to listen to music playlists and full music tracks for free using YouTube. To access the player, tap the "Play" icon at the bottom. You'll see a collection of playlists including your search history, favorites, and top songs across genres.
Tap on a playlist to start playing it. A small video window for the first track will pop up and start playing. To navigate through the playlist, swipe the video to the left or to the right.
Swipe up on the video to expand it and to see song lyrics. To stop playback at any time, swipe down.
You also have the option to play 30 second previews to quickly sample songs rather than listening to full tracks. You can set your default music playback settings at any time in the app settings.
